Cyanine3 NHS ester is a reactive dye for the labeling of amino-groups in biomolecules, an analog of Cy3® NHS ester. This reagent is ideal for the labeling of soluble proteins, peptides, and oligonucleotides/DNA. For delicate proteins consider using water-soluble sulfo-Cyanine3 NHS ester which does not require use of any co-solvent.
Cyanine3 NHS ester is a replacement for NHS esters of Cy3® and DyLight 549.
Cyanine3 NHS 酯是一种活性染料，用于标记生物分子中的氨基，是 Cy3® NHS 酯的类似物。 该试剂非常适合标记可溶性蛋白质、肽和寡核苷酸/DNA。 对于精细蛋白质，请考虑使用不需要使用任何助溶剂的水溶性磺基-Cyanine3 NHS 酯。
Cyanine3 NHS 酯是 Cy3® 和 DyLight 549 的 NHS 酯的替代品。
