Cyanine5 maleimide, Cy5 maleimide

Description

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._x000D_ _x000D_ Cyanine5 is an analog of Cy5, a common fluorophore which is compatible with various instrumentation like microscopes, imagers, and fluorescence readers._x000D_ _x000D_ For the labeling of antibodies and sensitive proteins we recommend to use the water soluble sulfo-Cyanine5 maleimide.
