Cyanine5-PEG4-COOH

中文名称：氰基-四聚乙二醇-羧酸

分子式：C43H60ClN3O7

分子量：766.4

结构式：

Cy5-PEG4-acid is a PEG linker containing a cyanine dye with excitation/emmission maximum 649/667 nm and a free terminal carboxyl acid. Terminal carboxylic acid can react with primary amine groups in the presence of of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydophilic PEG spacer increases solubility in aqueous media .

Cy5-PEG4-酸是一种PEG连接剂，含有激发/发射值为649/667nm的花青染料和游离末端羧酸。末端羧酸可在活化剂（例如EDC或HATU）存在下与伯胺基团反应，形成稳定的酰胺键。亲水性PEG间隔物增加了在水性介质中的溶解度。
