Blocking Agents

Blocking agents are non-fluorescent compounds that block the reactivity of the SNAP- or CLIP-tag intracellularly (SNAP-Cell® Block, NEB #S9106; and CLIP-Cell™ Block, NEB #S9220) or on the surface of live cells (SNAP-Surface® Block, NEB #S9143; and CLIP-Cell Block). They can be used to generate inactive controls in live cell labeling experiments performed with SNAP- or CLIP-tag fusion proteins.
