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
