BPG-0952 Pyrene-PEG-MAL, MW 1k-10k Inquiry

Synonyms: Pyrene-PEG-Maleimide

Pyrene-PEG-MAL, with a pyrene and a maleimide 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 fluorescent immunoassays to detect oxygen in cells and lipid vesicles. Pyrene-PEG-MAL reacts readily with free thiol groups at pH 6.5 to 7.5 to form stable thioether bonds. The reaction between maleimide and thiol groups makes the binding of pyrene to biomolecules simple and fast.
