compound introduction
Cy5 maleimide 是一种 CY 染料。CY 为花菁 (Cyanine) 的缩写，是由奇数个甲基单位连接的两个氮原子组成的化合物。菁类化合物具有波长长、吸收和发射可调、消光系数高、水溶性好、合成相对简单等特点。CY 系类染料常被用于蛋白，抗体以及小分子化合物的标记，对于蛋白抗体的标记，可以通过简单的混合反应来完成结合。 Cy5 maleimide is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis[1]. CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction.
