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