Cyanine5 tetrazine,Cy5 tetrazine Tetrazine-cyclooctene (TCO) ligation is one of the fastest bioconjugation reactions known to date. In order to use it for fluorescent labe生, a fluorescent reporter molecule bearing one of the reacting groups is necessary. Cyanine5 tetrazine is a molecule bearing Cyanine5 fluorophore, and tetrazine moiety. Cyanine5 is a very popular fluorophore compatible with numerous instruments.
