F1000Research 2023, 12 :308 ( https://doi.org/10.12688/f1000research.131333.1 ) First published: 21 Mar 2023, 12 :308 ( https://doi.org/10.12688/f1000research.131333.1 ) Latest published: 21 Mar 2023, 12 :308 ( https://doi.org/10.12688/f1000research.131333.1 ) Introduction Transmembrane protein 106B (TMEM106B) is a genetic risk variant for many neurodegenerative diseases. The presence of the TMEM106B major risk allele, rs1990622, is suspected to be a risk factor and disease modifier for Frontotemporal Dementia (FTD), with few studies investigating its potential role in Amyotrophic Lateral Sclerosis (ALS) pathogenesis. 1 – 5 TMEM106B is a transmembrane endosomal and lysosomal glycoprotein. The protein has garnered interest lately, with the discovery that a 135 amino acid portion of the protein from its luminal C-terminal domain forms fibrils in the brains of patients with frontotemporal lobar degeneration, progressive supranuclear palsy, and dementia with Lewy bodies. 6 , 7 The roles of TMEM106B fibrils in normal lysosomal function or disease pathogenesis are not known, nor is the mechanism by which the protein is proteolyzed, or forms fibrils. 7 Mechanistic studies would be greatly facilitated with the availability of high-quality validated antibodies. Here, we compared the performance of a range of commercially available antibodies for TMEM106B and characterized several high-quality antibodies for Western blot, immunoprecipitation and immunofluorescence, enabling biochemical and cellular assessment of TMEM106B properties and function. Results and discussion Our standard protocol involved comparing readouts from wild-type (WT) and knockout (KO) cells. 8 , 9 The first step was to identify a cell line(s) that expresses sufficient levels of TMEM106B to generate a measurable signal. To this end, we examined the DepMap transcriptomics databases to identify all cell lines that express the target at levels greater than 2.5 log 2 (transcripts per million “TPM” +1), which we have found to be a suitable cut-off (Cancer Dependency Map Portal, RRID:SCR_017655). Commercially available HAP1 cells expressed the TMEM106 B at RNA levels above the average range of cancer cells analyzed. The parental and KO HAP1 cell lines were obtained from Horizon Discovery ( Table 1 ). Table 1. Summary of the cell lines used. Institution Catalog number RRID (Cellosaurus) Cell line Genotype Horizon Discovery C631 CVCL_Y019 HAP1 WT Horizon Discovery HZGHC005877c010 CVCL_XU38 HAP1 TMEM106B KO For Western blot experiments, we resolved proteins from WT and TMEM106B KO cell extracts and probed them side-by-side with all antibodies in parallel ( Figure 1 ). Figure 1. Transmembrane protein 106B antibody screening by Western Blot. Lysates of HAP1 (WT and TMEM106B KO) were prepared and 15 μg of protein were processed for Western Blot with the indicated TMEM106B antibodies. The Ponceau stained transfers of each blot are presented are shown equal loading of WT and KO lysates and protein transfer efficiency from the acrylamide gels to the nitrocellulose membrane. Antibody dilutions were chosen according to the recommendations of the antibody supplier. Exceptions were given for antibodies 93334** and 60333-1-Ig*, which were titrated to 1/500 and 1/2000, respectively, as the signal was too weak when following the supplier’s recommendations. Antibody dilution used: ab244516 at 1/500, A20165 at 1/2000, 93334** at 1/500, 60333-1-lg* at 1/2000, PA5-34353 at 1/500, and PA5-63558 at 1/200.Predicted band size: 31 kDa. *= monoclonal antibody, **= recombinant antibody. For immunoprecipitation experiments, we used the antibodies to immunopurify TMEM106B from HAP1 cell extracts. The performance of each antibody was evaluated by detecting the TMEM106B protein in extracts, in the immunodepleted extracts and in the immunoprecipitates ( Figure 2 ). Figure 2. Transmembrane protein 106B antibody screening by immunoprecipitation. HAP1 lysates were prepared, and IP was performed using 2.0 μg of the indicated TMEM106B antibodies pre-coupled to Dynabeads protein G or protein A. Samples were washed and processed for Western Blot with the indicated TMEM106B antibody. For Western Blot, 93334** was used at 1/500. The Ponceau stained transfers of each blot are shown for similar reasons as in Figure 1 . SM=2% starting material; UB=2% unbound fraction; IP=immunoprecipitate; HC=antibody heavy chain. *= monoclonal antibody, **= recombinant antibody. For immunofluorescence, as described previously, antibodies were screened using a mosaic strategy. 10 In brief, we plated WT and KO cells together in the same well and imaged both cell types in the same field of view to reduce staining, imaging and image analysis bias ( Figure 3 ). Figure 3. Transmembrane protein 106B antibody screening by immunofluorescence. HAP1 WT and TMEM106B KO cells were labelled with a green or a far-red fluorescent dye, respectively. WT and KO cells were mixed and plated to a 1:1 ratio in a 96-well plate with a glass bottom. Cells were stained with the indicated TMEM106B antibodies and with the corresponding Alexa-fluor 555 coupled secondary antibody including DAPI. Acquisition of the blue (nucleus-DAPI), green (identification of WT cells), red (antibody staining) and far-red (identification of KO cells) channels were performed. Representative images of the merged blue and red (grayscale) channels are shown. WT and KO cells are outlined with green and magenta dashed line, respectively. When the concentration was not indicated by the supplier, we tested antibodies at 1/1000 or 1/2000. At this concentration, the signal from each antibody was in the range of detection of the microscope used. Antibody dilution used: ab244516 at 1/100, A20165 at 1/2000, 93334** at 1/100, 60333-1-lg* at 1/2000, PA5-34353 at 1/1000, and PA5-63558 at 1/100. Bars = 10 μm. *= monoclonal antibody, **= recombinant antibody. In conclusion, we have screened many TMEM106B commercial antibodies by Western blot, immunoprecipitation and immunofluorescence and identified several high-quality antibodies under our standardized experimental conditions.

Cell culture Both HAP1 WT and TMEM106B KO cell lines used are listed in Table 1 , together with their corresponding RRID, to ensure the cell lines are cited properly. 12 Cells were cultured in DMEM high glucose (GE Healthcare, cat. number SH30081.01) containing 10% fetal bovine serum (Wisent, cat. number 080450), 2 mM L-glutamate (Wisent, cat. number 609065), 100 IU penicillin and 100 μg/mL streptomycin (Wisent, cat. number 450201). Antibody screening by Western blot Western blot experiments were performed as described in our standard operating procedure. 13 HAP1 WT and TMEM106B KO were collected in RIPA buffer (25mM Tris-HCl pH 7.6, 150mM NaCl, 1% NP-40, 1% sodium deoxycholate, 0.1% SDS) from Thermo Fisher Scientific (cat number 0089901), supplemented with 1x protease inhibitor cocktail mix from MilliporeSigma (cat. number 78429). Lysates were sonicated briefly and incubated for 30 min on ice. Lysates were spun at ~110,000 x g for 15 min at 4°C and equal protein aliquots of the supernatants were analyzed by SDS-PAGE and Western Blot. BLUelf prestained protein ladder from GeneDireX (cat. number PM008-0500) was used. Western blots were performed with pre-cast mini 4-15% gradient polyacrylamide gels from Bio-Rad (cat. number 4561084) and transferred on nitrocellulose membranes. Proteins on the blots were visualized with Ponceau staining which is scanned to show together with individual Western blots. Blots were blocked with 5% milk for 1 h, and antibodies were incubated overnight at 4°C with 5% bovine serum albumin (BSA) (Wisent, cat. number 800-095) in TBS with 0,1% Tween 20 (TBST) (Cell Signaling Technology, cat. number 9997). Following three washes with TBST, the peroxidase conjugated secondary antibody was incubated at a dilution of ~0.2 μg/mL in TBST with 5% milk for 1 hr at room temperature followed by three washes with TBST. Membranes are incubated with Pierce ECL from Thermo Fisher Scientific (cat. number 32106) prior to detection with HyBlot CL autoradiography films from Denville (cat. number 1159T41). Antibody screening by immunoprecipitation Immunoprecipitation was performed as described in our standard operating procedure. 14 Antibody-bead conjugates were prepared by adding 2 μg of antibody to 500 μL of Pierce IP Lysis Buffer from Thermo Fisher Scientific (cat. number 87788) in a 1.5 mL microcentrifuge tube together with 30 μL of Dynabeads protein A- (for rabbit antibodies) or protein G- (for mouse antibodies) from Thermo Fisher Scientific (cat. number 10002D and 10004D, respectively). Tubes were rocked ~2 hours at 4°C followed by several washes to remove unbound antibodies. HAP1 WT were collected in Pierce IP buffer (25 mM Tris-HCl pH 7.4, 150 mM NaCl, 1 mM EDTA, 1% NP-40 and 5% glycerol) from Thermo Fisher Scientific (cat. number 87788), supplemented with protease inhibitor from MilliporeSigma (cat. number P8340). Lysates were rocked for 30 min at 4°C and spun at 110,000 x g for 15 min at 4°C. 0.5 mL aliquots at 2.0 mg/mL of lysate were incubated with an antibody-bead conjugate for ~2 hrs at 4°C. The unbound fractions were collected, and beads were subsequently washed three times with 1.0 mL of IP lysis buffer and processed for SDS-PAGE and Western blot on a pre-cast mini 4-15% polyacrylamide gel. Prot-A:HRP (MilliporeSigma, cat. number P8651) was used as a secondary detection system at a dilution of 0.4 μg/mL. Antibody screening by immunofluorescence Immunofluorescence was performed as described in our standard operating procedure. 10 HAP1 WT and TMEM106B KO were labelled with CellTracker green (Thermo Fisher Scientific, cat. number C2925) or CellTracker deep red (Thermo Fisher Scientific, cat. number C34565) fluorescence dye, respectively. The nuclei were labelled with DAPI (Thermo Fisher Scientific, cat. number D3571) fluorescent stain. WT and KO cells were plated in 96 well glass plates (Perkin Elmer, cat. number 6055300) as a mosaic and incubated for 24 hrs in a cell culture incubator at 37 o C, 5% CO 2 . Cells were fixed in 4% paraformaldehyde (PFA) (Beantown chemical, cat. number 140770-10mL) in phosphate buffered saline (PBS) (Wisent, cat. number 311-010-CL) for 15 min at room temperature and then washed three times with PBS. Cells were permeabilized in PBS with 0.1% Triton X-100 (Thermo Fisher Scientific, cat. number BP151-500) for 10 min at room temperature and blocked with PBS containing 5% BSA, 5% goat serum (Gibco, cat. number 16210-064) and 0.01% Triton X-100 for 30 min at room temperature. Cells were incubated with IF buffer (PBS, 5% BSA, 0.01% Triton X-100) containing the primary TMEM106B antibodies overnight at 4°C. Cells were then washed 3 × 10 min with IF buffer and incubated with the corresponding Alexa Fluor 555-conjugated secondary antibodies in IF buffer at a dilution of 1.0 μg/mL for 1 hr at room temperature with DAPI. Cells were washed 3 × 10 min with IF buffer and once with PBS. Images were acquired on an ImageXpress micro widefield high-content microscopy system (Molecular Devices), using a 20x/0.45 NA air objective lens and scientific CMOS camera (16-bit, 1.97mm field of view), equipped with 395, 475, 555 and 635 nm solid state LED lights (Lumencor Aura III light engine) and bandpass emission filters (432/36 nm, 520/35 nm, 600/37 nm and 692/40 nm) to excite and capture fluorescence emission for DAPI, CellTracker Green, Alexa fluor 555 and CellTracker Red, respectively. Images had pixel sizes of 0.68 × 0.68 microns. Exposure time was set with maximal (relevant) pixel intensity ~80% of dynamic range and verified on multiple wells before acquisition. Since the IF staining varied depending on the primary antibody used, the exposure time was set using the most intensely stained well as reference. Frequently, the focal plane varied slightly within a single field of view. To remedy this issue, a stack of three images per channel was acquired at a z-interval of 4 microns per field and best focus projections were generated during the acquisition (MetaXpress v6.7.1, Molecular Devices). Segmentation was carried out on the projections of CellTracker channels using CellPose v1.0 on green (WT) and far-red (KO) channels, using as parameters the ‘cyto’ model to detect whole cells, and using an estimated diameter tested for each cell type, between 15 and 20 microns. 15 Masks were used to generate cell outlines for intensity quantification. Figures were assembled with Adobe Illustrator.

Continue reading READ ALL In their article, Ayoubi and colleagues are reporting about their quality tests of six different commercial anti-TMEM106B antibodies using Western blotting, immunoprecipitation, and immunocytochemistry. The article is interesting and useful for groups working with this protein. Doing KO controls to test antibodies is considered the gold standard of validation tests. Nevertheless, unfortunately it is not done very often. That’s why I appreciate the work of these authors. I would consider the following concerns. MAJOR CONCERNS: 1) Chapter: “Results and discussion”: In my experience it is common to describe the results in the result chapter instead of just referring to the figures. There is no discussion in this chapter yet. The authors should interpret their results in a more concrete way. Which antibodies do they recommend for which method? Interesting to mention in my eyes: 2 out of 6 tested antibodies don’t work in Western blotting, as they don’t bind the protein of interest, but they nonspecifically bind other proteins. One further antibody (60333-1-lg) nonspecifically binds other proteins in addition to binding the protein of interest. In total, half of the antibodies show unspecific binding, which could harm result interpretation when using this antibody without having a KO control. Article type "Data Note": In my perspective this article is not a "data note" in the classical sense (Journal info: "Data Notes are brief descriptions of datasets that promote the potential reuse of research data and include details of why and how the data were created; they do not include any analyses or conclusions"). The authors do not present a classical data set however. To me, an analysis and conclusions are necessary. Hence, I would ask the authors to consider another article type. Is there something like a "Technical note"? MINOR CONCERNS: In their introduction, the authors speak of “a 135 amino acid portion of the protein from its luminal C-terminal domain”, that might play a pathophysiological role. Given this information, it might be interesting which of the six antibodies have epitopes in that specific domain. I there any information available? Some ideas to address this questions methodologically ? Results and discussion: “For Western blot experiments, we resolved proteins from WT and TMEM106B KO cell extracts and probed them side-by side with all antibodies in parallel (Figure 1).” What means “side-by side” here? Do they come from the same membrane in order to avoid membrane-to-membrane variation? In the best case, in future experiments, the authors could even considering cutting the lanes vertically in order to even avoid lane-to-lane variation (cf. Pubmed ID 30768763). Figure 1, panel PA5-34353: I am a bit surprised that the “scratches” and inhomogenities in protein transfer is not equally visible in the total protein staining (ponceau). I would kindly ask the authors to check in their data files that the ponceau staining is really originating from the same membrane, because the loading control would be invalid otherwise. Figure 2: Why is “HC” (antibody heavy chain) only shown in the second panel? I would recommend showing it in the first panel only, or in all panels. Figure 2: I do not understand why there is written “WB: 93334**” below each of the 6 Western blots. Figure 3: Is the Alexa-fluor 555 not interfering with the fluorescence stainings that were applied to distinguish WT from KO? Concluding sentence in the results section: “we have screened many TMEM106B commercial antibodies” I recommend avoiding vague words like “many” where a more concrete indication (“six”) is possible. Same for the word “several” in the same sentence. Is the rationale for creating the dataset(s) clearly described? Yes Are the protocols appropriate and is the work technically sound? Yes Are sufficient details of methods and materials provided to allow replication by others? Yes Are the datasets clearly presented in a useable and accessible format? Yes Competing Interests: No competing interests were disclosed. Reviewer Expertise: Western blotting, antibodies, autoantibodies, ELISA, method development I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.

Continue reading READ ALL This is a useful paper, highlighting the need for antibody validation. There is important information here for TMEM106B antibody users and clear methodology for those wishing to test antibodies in their own area. Experiments are well carried out and well controlled, and figures are clear. The lack of results analysis means that figures can be interpreted by the reader for their own experimental needs, however, any misinterpretation by a reader could be avoided by adding a column to Table 2 showing the study findings alongside ‘Vendors recommended applications’. The number of technical replicates for each method should be stated. Full blots could be shown for immunoprecipitation results (Figure 2). I would have found figures easier to understand with consistent naming of HAP1 WT and KO cells as HAP1 WT and HAP1 KO rather than a combination of WT and THEM106B KO (Figure 1), HAP1 (Figure 2) and WT and KO (Figure 3). Units could be added to the markers in Figures 1 and 2. Is the rationale for creating the dataset(s) clearly described? Yes Are the protocols appropriate and is the work technically sound?

In total, half of the antibodies show unspecific binding, which could harm result interpretation when using this antibody without having a KO control. Article type "Data Note": In my perspective this article is not a "data note" in the classical sense (Journal info: "Data Notes are brief descriptions of datasets that promote the potential reuse of research data and include details of why and how the data were created; they do not include any analyses or conclusions"). The authors do not present a classical data set however. To me, an analysis and conclusions are necessary. Hence, I would ask the authors to consider another article type. Is there something like a "Technical note"? MINOR CONCERNS: In their introduction, the authors speak of “a 135 amino acid portion of the protein from its luminal C-terminal domain”, that might play a pathophysiological role. Given this information, it might be interesting which of the six antibodies have epitopes in that specific domain. I there any information available? Some ideas to address this questions methodologically ? Results and discussion: “For Western blot experiments, we resolved proteins from WT and TMEM106B KO cell extracts and probed them side-by side with all antibodies in parallel (Figure 1).” What means “side-by side” here? Do they come from the same membrane in order to avoid membrane-to-membrane variation? In the best case, in future experiments, the authors could even considering cutting the lanes vertically in order to even avoid lane-to-lane variation (cf. Pubmed ID 30768763). Figure 1, panel PA5-34353: I am a bit surprised that the “scratches” and inhomogenities in protein transfer is not equally visible in the total protein staining (ponceau). I would kindly ask the authors to check in their data files that the ponceau staining is really originating from the same membrane, because the loading control would be invalid otherwise. Figure 2: Why is “HC” (antibody heavy chain) only shown in the second panel? I would recommend showing it in the first panel only, or in all panels. Figure 2: I do not understand why there is written “WB: 93334**” below each of the 6 Western blots. Figure 3: Is the Alexa-fluor 555 not interfering with the fluorescence stainings that were applied to distinguish WT from KO? Concluding sentence in the results section: “we have screened many TMEM106B commercial antibodies” I recommend avoiding vague words like “many” where a more concrete indication (“six”) is possible. Same for the word “several” in the same sentence. Is the rationale for creating the dataset(s) clearly described? Yes Are the protocols appropriate and is the work technically sound? Yes Are sufficient details of methods and materials provided to allow replication by others? Yes Are the datasets clearly presented in a useable and accessible format? Yes Competing Interests No competing interests were disclosed. Reviewer Expertise Western blotting, antibodies, autoantibodies, ELISA, method development I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above. reply Respond to this report Responses (0) Moritz CP.

Not approved Fundamental flaws in the paper seriously undermine the findings and conclusions This is a useful paper, highlighting the need for antibody validation. There is important information here for TMEM106B antibody users and clear methodology for those wishing to test antibodies in their own area. Experiments are well carried out and well controlled, and figures are clear. The lack of results analysis means that figures can be interpreted by the reader for their own experimental needs, however, any misinterpretation by a reader could be avoided by adding a column to Table 2 showing the study findings alongside ‘Vendors recommended applications’. The number of technical replicates for each method should be stated. Full blots could be shown for immunoprecipitation results (Figure 2). I would have found figures easier to understand with consistent naming of HAP1 WT and KO cells as HAP1 WT and HAP1 KO rather than a combination of WT and THEM106B KO (Figure 1), HAP1 (Figure 2) and WT and KO (Figure 3). Units could be added to the markers in Figures 1 and 2. Is the rationale for creating the dataset(s) clearly described? Yes Are the protocols appropriate and is the work technically sound?
