BDP FL-PEG8-NHS ester is a BDP dye linker containing a NHS ester group and a hydrophilic PEG spacer arm. The NHS ester allows the dye to react with primary amines and the hydrophilic PEG spacer arm increases water solubility as well as membrane permability. This dye is used for protein and peptide labeing and is photostable. BDP FL-PEG8-NHS ester is a green-fluorescent dye and has several characteristics that make it potentially superior in some applications, including high extinction coefficient, high fluorescence quantum yield, narrow emission bandwidth, red shift in fluorescence emission at high dye concentrations, relatively long excited-state lifetime, etc. Reagent grade, for research purpose.
