Bis-Bromoacetamido-dPEG®11, product number QBD-11338, is a thiol-reactive, homobifunctional crosslinker, with the two reactive ends separated by a medium-length (44 atoms, 47.5 Å), single molecular weight, discrete polyethylene glycol (dPEG®) spacer. Both ends of the dPEG® spacer terminate with bromoacetyl groups that connect to the dPEG® crossbridge through amide bonds.
Bromoacetyl-functionalized reagents are useful alternatives to maleimide-functionalized reagents. The bromoacetyl group reacts with sulfhydryl groups at pH 8 or higher. Maleimide groups are chemoselective for thiols at pH 6.5 – 7.5 and lose selectivity at higher pH values. Bromoacetyl-thiol reaction rates are somewhat slower than maleimide-thiol reaction rates.
