Fluorescent dye derived from trimethine cyanine. Zwitterion, and forms a stable covalent bond with thiols at pH >7.5.
Store in the dark at -20°C.
Maximum Excitation/Emission wavelength: 551/567 nm (in CH3OH)
Suitable for 2D-DIGE (2-dimensional difference gel electrophoresis) in saturation labeling applications, the intrinsic neutral charge does not alter the pI (isoelectric point) of the biomolecule after labeling on the cysteine groups.
