BPG-0942 Pyrene-PEG-COOH, MW 1k-10k Inquiry

Pyrene-PEG-COOH, with a pyrene and a carboxyl group at each end of the molecular chain, is a fluorescent heterofunctional PEG derivative. It can label proteins, antibodies, peptides, nucleic acids or particles. Pyrene is a unique fluorescent dye with an exceptionally long excited state lifetime (>100 ns). The long excited state lifetime of this dye allows it to be used in time-resolved fluorescence immunoassays to detect oxygen in cells and lipid vesicles. Pyrene-PEG-COOH can react with amino groups and thus attach to biomolecules or cell surfaces. PEG linkers between pyrene and carboxylic acid groups offer better water solubility, fewer steric hindrances and higher stability.
