Apexbio Technology LLC Cy5.5 carboxylic acid (non-sulfonated) 25mg

Supplier: Apexbio Technology LLC A813425
Cy5 5 carboxylic acid (non-sulfonated) is a near-infrared (NIR) fluorescent dye with excitation and emission wavelengths at approximately 673 nm and 707 nm respectively Its non-reactive carboxyl group lacks spontaneous coupling activity making it suitable as a reference fluorophore or control in labeling experiments fluorescence calibration and imaging studies Due to limited solubility in aqueous buffers it typically requires prior dissolution in organic solvents before use in biomolecule conjugation or in vivo administration In biomedical imaging Cy5 5 carboxylic acid serves as a control agent to assess dye diffusion and drug-release kinetics under NIR-induced stimuli within hydrogel-based drug delivery platforms
