Bromo PEG linkers are PEG derivatives containing a terminal bromide group on one end and another functional group on the other end.
The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. Various bromo PEG linkers have been used for bio-conjugation through the formation of a sulfide bond with thiol moieties on bio-molecules.
