Capture and Purification of Plant Genomic DNA on a Readily-available Cellulose Matrix

Whatman FTA ®Cards are a fast and efficient method for capturing and storing nucleic acids but are cost-prohibitive for some researchers. We developed a method that substitutes readily-available cellulose-based paper and homemade washing buffer for commercial FTA ®Cards and FTA ®Purification Reagent. This method is suitable for long-term storage of DNA from many plant species, including Arabidopsis thaliana , prior to purification and PCR. Method Summary Here we report a low-cost method for long-term storage of plant genomic DNA on a readily available cellulose matrix.
