cy7 se triethylamine (477908 53 5(free acid) )

CY7-SE Triethylamine is a fluorescence labeling agent (Ex=700-770 nm,Em=790 nm) used for labeling proteins, peptides, antibodies, and oligonucleotides.

CY7-SE is a CY7-derived dye with excitation/emission wavelengths of 750/775 nm. CY7 (Sulfo-Cyanine7) is an amine-reactive near-infrared (NIR) fluorophore with excitation/emission wavelengths of 745/800 nm, suitable for in vivo imaging, flow cytometry, antibody labelling, and nucleic acid detection, among other applications.

CY7-SE triethylamine is a type of CY dye. CY stands for cyanine, which is a compound formed by two nitrogen atoms linked by an odd number of methine units. Cyanine compounds are known for their long wavelengths, adjustable absorption and emission, high extinction coefficients, good water solubility, and relatively simple synthesis. CY series dyes are commonly used for labeling proteins, antibodies, and small molecule compounds. For protein and antibody labeling, they can be conjugated through straightforward mixing reactions. Below, we detail a method for labeling proteins and antibodies, which can serve as a useful reference.
