Cyanine5.5 tetrazine,Cy5.5 tetrazine Cyanine5.5 is a far red emitting dye for in vivo imaging and applications requiring low background. This Cyanine5.5 derivative contains tetrazine moiety that reacts with trans-cyclooctenes, cyclopropenes, and some strained cyclooctynes with the formation of stable conjugates. This labe生 reaction is extremely fast, and can be used in vivo.
