Cy7.5 NHS ester is a NIR dye with low aqueous solubility and long-wave emission. This labeling reagent is amine-reactive derivative of this fluorophore. In vivo, near infrared radiation can be used for imaging applications for it readily penetrates tissues. This product can be used for the labeling of various biomolecules such as proteins and peptides which contain amine groups, to track their distribution in organism in vivo. For biomolecule labeling, the labeling reagent has low aqueous solubility, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer.
In mice, Cy7.5 NHS ester labeled insulin (Cy7.5-INS) and were injected via subcutaneous injection at insulin dose of 1 IU/kg. The biodistribution of Cy7.5-Labeled insulin, INS/HTCC, and INS/HTCC-CA11 Nanoparticles was easily analyzed [1].

体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
