Bis-PEG15-acid is a homobifunctional PEG derivative which will react with an amine-containing moiety in the presence of a coupling reagent. Bis PEGs can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups. It can also be converted to N-hydroxysuccinimide active esters which can be widely used in bioconjugation.
