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

Supplier:  Apexbio Technology LLC A813325

Cy5 carboxylic acid (non-sulfonated) is a non-reactive near-infrared fluorescent dye with excitation and emission maxima at approximately 649 nm and 670 nm respectively This dye exists as a free carboxyl form that lacks reactive functional groups thus limiting direct coupling to biomolecules Due to its limited solubility in aqueous buffers an organic solvent is typically employed to prepare stock solutions prior to experimental applications Cy5 carboxylic acid primarily serves as a fluorescence reference standard or negative control in bioconjugation and labeling experiments and is also applicable in instrument calibration and optimization Additionally the non-reactive dye can be used to monitor cellular uptake pathways evaluate protein expression efficiency and study dye distribution patterns within cells
