  • 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.

    ACP/MCP-tag substrates are conjugated to the phosphopantetheinyl moeity of Coenzyme A (CoA) and require a separate enzyme (ACP or SFP Synthase) for labeling. The labeling reaction is specific for fusion proteins expressed on the cell surface. The same substrates are used to label both the ACP- and the MCP-tags; specificity is determined by the synthase used for labeling.
