Cy7 maleimide is a near-infrared, sulfhydryl reactive dye which has low aqueous solubility. This reagent can label the proteins contain free sulfhydryl groups. Labeled proteins thus obtained are used in NIR bioimaging applications. In tissues or in live organism, NIR imaging systems can be used to visualize distribution of labeled proteins. 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 splenocytes, for ease of detection, P22 particles were labeled internally with Cy7-maleimide. P22-Cy7 alone or P22-Cy7 decorated with DecSelf was incubated with splenocytes at 37℃ to encourage phagocytosis [1].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
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。
