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 labeling reaction is extremely fast, and can be used in vivo.
Cy5.5 是一种远红发射染料，适用于体内成像和需要低背景的应用。 这种 Cy5.5 衍生物含有四嗪部分，可与反式环辛烯、环丙烯和一些应变的环辛炔反应形成稳定的共轭物。
这种标记反应非常快，可以在体内使用。
