At 20 kDa, SNAP tag is smaller than HaloTag (33 kDa), potentially reducing interference with the tagged proteins function. SNAP tag reacts with covalently with benzylguanine (BG)or chloropyrimidine (CP) derivatives, forming a stable thioether bonds that ensures durability for long term experiments or harsh conditions. SNAP tag can be used alongside other tags
