It is also a self labeling protein derived from human O6 alkylguanine DNA alkyltransferase. Unlike the SNAP tag, which reacts with benzylguanine (BG)or chloropyrimidine (CP) derivatives, the CLIP tag is engineered to specifically interact with benzylcytosine (BC)derivatives. This modification allows for distinct labeling applications, enabling researchers to use both SNAP tag and CLIP tag in the same
