VNIRTM 6-CFDA NHS Ester (single isomer) All Products Cell Biology  VNIR 207 Description VNIRTM 6-CFDA NHS Ester is a fluorescein-based membrane permeable, non-fluorescent precursor of carboxyfluorescein. It is reactive to amines and forms FDA conjugates. This dye finds its application in labelling primary cells, cell lines and cell proliferation assay with the fluorescent readout. It gets equally distributed between the progenies. The dye diffuses into the cell passively and covalently label intracellular proteins resulting in long term labelling. CFDA-NHS staining can also be used for motility assays and in-vivo tracking of cells. This hydrophobic dye is hydrolysed enzymatically to a hydrophilic, strongly fluorescent carboxyfluorescien intracellularly. This dye is known to have high retention capability inside the cell. Synonyms CFDA-SE, CFSE, 6-Carboxyfluorescein Diacetate Succinimidyl Ester Cat. No. VNIR207 Molecular weight 557.46 Molecular formula C29H19NO11 Appearance White to off-white powder Spectral property Excitation: 494nm; Emission: 521nm (hydrolysed product) Purity ≥ 95% (HPLC) Solubility Acetone, DMSO and DMF Storage conditions -20°C (protect from light and moisture) References Please let us know if you publish your research using VNIRTM 6-CFDA NHS Ester.
