SNAP-Surface® Block

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 is largely membrane impermeable essentially limiting blocking to cell surface-exposed SNAP-tags
  • Once it reacts with the SNAP-tag, it irreversibly inactivates it for subsequent labeling steps
  • It can be used to generate inactive controls in live cell labeling experiments performed with SNAP-tag fusion proteins
