VNIRTM Sulfo-Cyanine5 NHS Ester All Products Conjugative Dyes And Reagents VNIR 406 Description VNIRTM Sulfo-Cyanine5 NHS ester is a sulfonated and highly water soluble analog of Cyanine5 NHS ester. This is a red emitting fluorescent dye used for the amino-group labelling in proteins, peptides, antibodies, oligonucleotides/DNA and any amine containing molecules. This dye can be used without any organic co-solvent and particurlarly useful for biomolecules which degrade in the presence of organic co-solvent and for protein with low solubility. Cat. No. VNIR406 Molecular weight 739.86 Molecular formula C36H41N3O10S2 Appearance Dark blue powder Purity ≥95% (HPLC) Spectral property Excitation: 646nm, Emission: 668nm Storage conditions -20°C (protect from light and moisture) References Please let us know if you publish your research using VNIRTM Sulfo-Cyanine5 NHS Ester.
