    SNAP-tag® Substrates

    SNAP-tag®, CLIP-tag™ and ACP/MCP-tag Substrate Selection Chart

    NEB offers a large selection of fluorescent labels (substrates) for SNAP-, CLIP-, ACP- and MCP-tag fusion proteins.

    NEB offers a large selection of fluorescent labels (substrates) for SNAP-fusion proteins. SNAP-tag® substrates consist of a fluorophore conjugated to guanine or chloropyrimidine leaving groups via a benzyl linker. Substrates label the SNAP-tag® without the need for additional enzymes. Cell-permeable substrates (SNAP-Cell®) are suitable for both intracellular and cell-surface labeling, whereas non-cell-permeable substrates (SNAP-Surface®) are specific for fusion proteins expressed on the cell surface only.
