Cyanine5.5 NHS ester is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides, an analog of Cy5.5® NHS ester.
Cy5.5 is a far-red (and near-infrared) emitting dye which is ideal for fluorescence measurements where background fluorescence is a concern. It is also suitable for in vivo NIR imaging experiments.
This reagent can replace NHS esters of Cy5.5® and DyLight 680.
Cyanine5.5 NHS 酯是一种活性染料，用于标记肽、蛋白质和寡核苷酸中的氨基，是 Cy5.5® NHS 酯的类似物。
Cy5.5 是一种远红（和近红外）发射染料，非常适合需要考虑背景荧光的荧光测量。 它也适用于体内近红外成像实验。
该试剂可替代 Cy5.5® 和 DyLight 680 的 NHS 酯。
