ReadiUse(TM) Preactivated PE-Cy5.5 Maleimide

Extinction coefficient (cm -1 M -1): 1960000. Excitation (nm): 566. Emission (nm): 671. PE-Cy5.5 is a popular tandem color used in flow cytometry. Its primary absorption peak is at 565 nm with emission peak at ~700 nm. AAT Bioquest offers this preactivated PE-Cy5.5 maleimide to facilitate the PE-Cy5.5 tandem conjugations to antibodies and other proteins such as streptavidin and other secondary reagents. It is prepared from the commonly used crosslinker SMCC. Our preactivated PE-Cy5.5 maleimide is ready to conjugate the reduced antibodies and other thiol-containing biomolecules.
