The SNAP-tag is a novel tool for protein research, allowing the specific, covalent attachment of virtually any molecule to a protein of interest. The SNAP-tag is a small protein based on mammalian O6-alkylguanine-DNA-alkyltransferase (AGT). SNAP-tag substrates are derivatives of benzylpurines and benzylchloropyrimidines. In the labeling reaction, the substituted benzyl group of the substrate is covalently attached to the SNAP-tag.SNAP-tag Purified Protein can be used as a positive control for in vitro labeling with various SNAP-tag fluorescent substrates. The coding sequence of SNAP-tag was cloned into a pTXB1 derived E. coli T7 expression vector. SNAP-tag protein (MW: 19,694) was expressed and purified according to the instructions in the IMPACT™ kit manual (NEB #E6901). The purified SNAP-tag protein was dialyzed into 1X phosphate buffered saline (PBS) solution containing 1 mM DTT at 1mg/ml (50 μM) and stored at -80°C. Mass spectrometry analysis indicates the SNAP-tag purified protein has two species with molecular weights of 19,694 and 19,829 (with a C-terminal DTT moiety attached).
