SNAP-tag is a protein tag of 20 kD and specifically reacts with its benzylguanine (BG) substrates, thereby forming a covalent, thus highly stable thioether bond. SNAP-tag substrates are chemically stable and are not reactive to other proteins. Applications range from intracellular and cell surface labeling, over simplified detection on an SDS-PAGE, to kits for pull down assays and purification of fusion proteins.
Our kits include a free license even allowing commercial use of SNAP-tag (such as contract research).
