BDP FL L-cystine is a symmetric disulfide for reversible thiol-specific labeling of thiolated oligonucleotides, proteins, and cells.
BDP FL L-cystine consists of two BDP FL molecules connected via a disulfide bridge between two cysteine residues. In the dimeric disulfide state, the fluorescence of the dye is quenched.
Like other symmetric disulfides, BDP FL L-cystine undergoes a thiol-disulfide interchange reaction. Reduction of the disulfide bridge releases the monomeric dye molecule and results in fluorescence in the green region of the spectrum.
