SNAP Companion

The non-overlapping substrate specificity of SNAP-tag® and CLIP-tag™ enables the orthogonal and complementary labeling of two proteins simultaneously in the same cell. Furthermore, SNAP-tag and CLIP-tag based pulse-chase experiments allow for visualization of different generations of proteins and analysis of protein turnover in living cells (1-3). Additionally, there are a numbers of companion products designed to enable a wide variety of other applications including: Biotin substrates, SDS-PAGE specific SNAP-tag and CLIP-Vista labels, non-fluorescent blocking agents, resin and magnetic beads for pull-down applications, building blocks for the generation of custom substrates, and a SNAP-tag specific purified protein and antibody.

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.
