产品描述
Cyanine5 maleimide is a mono-reactive dye which selectively couples with thiol groups (for example, with cysteines in peptides and proteins) to give labeled conjugates.Cyanine5 is an analog of Cy5®, a common fluorophore which is compatible with various instrumentation like microscopes, imagers, and fluorescence readers.For the labeling of antibodies and sensitive proteins we recommend to use the water solublesulfo-Cyanine5 maleimide.
