An activated cyanine fluorescent dye for covalent labeling of proteins, antibodies and other amine-containing molecules.
MCE Cyanine5.5 NHS Ester (HY-D0925), listed by the manufacturer as Cy5.5-SE, is a reactive cyanine dye for preparing fluorescent molecular conjugates. Its NHS ester group reacts with primary amines to attach the fluorophore covalently.
The reagent supports antibody and protein labeling as well as fluorescent small-molecule probe preparation. Conjugation should use compatible buffers without competing primary amines, followed by removal of unreacted dye. MedChemExpress
