Bis-sulfone-PEG12-NHS Ester

Overview

Bis-sulfone-PEG12-NHS Ester is a bis-alkylating labeling reagent that is selective for the cysteine sulfur atoms from a native disulfide. These reagents undergo bis-alkylation to conjugate both thiols derived from the two cysteine residues of a reduced native disulfide bond such as the interchain disulfide bonds of an antibody. The reaction results in covalent rebridging of the disulfide bond via a three carbon bridge leaving the protein structurally intact. The hydrophilic PEG spacer increases solubility in aqueous media.
