TC-FlAsH™ TC-ReAsH™ labeling products for tetracysteine tags

The TC-FlAsH™ TC-ReAsH™ labeling products are based on the FlAsH and ReAsH tetracysteine tag technology developed by Tsien and colleagues. The technology consists of two nonfluorescent biarsenical compounds that become highly fluorescent upon binding to a specific sequence tetracysteine motif. The best protein sequence for biarsenical compound binding is CCPGCC. The TC-FlAsH™ TC-ReAsH™ labeling products provide researchers with a unique set of tools for studying cellular processes and pathways with the following features:

  • Quick tagging—proteins can be visualized as soon as translation occurs
  • Convenience—tetracysteine tag can be easily subcloned onto the protein expression sequence of interest
  • Reliability—small tetracysteine tag does not interfere with the behavior endogenous proteins
  • Multiplexing flexibility—choice of green or red labeling on tetracysteine tagged protein
  • Low background—new wash buffer greatly reduces nonspecific staining

Choice of fluorescent colors using the TC-FlAsH™ TC-FlAsH™ II In-Cell Tetracysteine Tag Detection Kit. An actin–TC-Tag fusion protein was used in a transient transfection experiment of CHO cells. Separate samples of transfected cells were stained with FlAsH-EDT2 labeling reagent (left) and ReAsH-EDT2 labeling reagent (right). Actin staining is very strong in both samples; only a low level of background fluorescence is seen in the nontransfected neighboring cells. The experiment shows that a single tagged protein can be detected with either a green- or red-fluorescent label.
