Abstract

Abstract Bacterial expression and purification of de novo designed mini-fluorescence-activating proteins (mFAPs) are accomplished by genetically fusing mFAP variants to an N-terminal 6xHis tag and optionally to a Tobacco Etch Virus (TEV) protease epitope. The protocol can take less than 24 hours to complete, and allows for downstream in vitro characterization of photophysical properties of mFAPs by equilibration with exogenous fluorogenic compounds.
