SNAP-Surface® Block (C8 propanoic acid benzylguanine, CBG) is a nonfluorescent compound that blocks the reactivity of the SNAP-tag® in solution or on the surface of living cells
It can be used to generate inactive controls in live cell labeling experiments performed with SNAP-tag fusion proteins. SNAP-Surface Block reacts with the SNAP-tag irreversibly, inactivating it for subsequent labeling steps. This blocker is largely membrane impermeable essentially limiting blocking to cell surface-exposed SNAP-tags.
