BGSN3

BGSN3 is a good substrate for the SNAP-tag and H5 enzymes. The activities of SNAP-tag and H5 enzymes on BGSN3 are reasonable (IC50=17.8 and 10 μM, respectively)[1]. BGSN3 is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
