GC68918

Cy5·5-SE

Also known as 2-[5-[3-[6-(2,5-dioxopyrrolidin-1-yl)oxy-6-oxohexyl]-1,1-dimethyl-6,8-disulfobenzo[e]indol-3-ium-2-yl]penta-2,4-dienylidene]-3-ethyl-1,1-dimethyl-8-sulfobenzo[e]indole-6-sulfonate

Cy5·5-SE (Cyanine5·5 NHS ester) is a type of CY dye· CY stands for Cyanine, which is a compound composed of two nitrogen atoms connected by an odd number of methyl units· Cyanine compounds have characteristics such as long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility, and relatively simple synthesis· CY series dyes are often used to label proteins, antibodies and small molecules· For labeling protein antibodies, binding can be completed through a simple mixing reaction· The following describes the labeling method for protein antibody labeling and has some reference value· Storage: Avoid light
