DESCRIPTION
Cyanine3 Carboxylic Acid is a non-activated, non-sulfonated fluorescent dye featuring a terminal carboxyl group. It displays strong orange-red fluorescence and is soluble in polar organic solvents (e.g., DMSO, DMF), though poorly miscible in aqueous solutions. This compound serves as a non-reactive reference fluorophore for calibration, negative controls, or as a precursor for synthesizing activated derivatives.
For covalent conjugation to amine-containing biomolecules (e.g., proteins, peptides), use Cyanine3 NHS ester or its water-soluble sulfonated variant (sulfo-Cyanine3 NHS ester). Store under anhydrous conditions, shielded from light.
