MeCY5-NHS ester triethylamine（Cat No.:I041380）is a fluorescent labeling reagent used in biochemical and molecular biology applications. It consists of a Cy5 fluorophore (a bright, far-red fluorescent dye) linked to an N-hydroxysuccinimide (NHS) ester, which facilitates covalent bonding to primary amines on biomolecules like proteins or nucleic acids. Triethylamine is used as a base to neutralize the reaction by-products and to help maintain the stability of the NHS ester during the coupling process. MeCY5-NHS ester triethylamine is widely used in fluorescence-based assays, imaging, and diagnostics for visualizing biomolecular interactions and tracking molecules in research.
