SNAP-Cell® Block

SNAP-Cell® Block (bromothenylpteridine, BTP) is a non-fluorescent compound that blocks the reactivity of the SNAP-tag® in solution or in living cells.

  • SNAP-Cell Block is highly membrane permeable
  • Once it reacts in the cell 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
