CLIP Cell

CLIP-tag is a modified version of SNAP-tag®, engineered to react with benzylcytosine rather than benzylguanine derivative substrates. When used in conjunction with SNAP-tag, CLIP-tag enables the orthogonal and complementary labeling of two proteins simultaneously in the same cells.

Protein Labeling with SNAP-tag and CLIP-tag

The SNAP- (gold) or CLIP-tag (purple) is fused to the protein of interest (blue). Labeling occurs through covalent attachment to the tag, releasing either a guanine or a cytosine moiety.
