Application

A heterobifunctional cross-linking reagent which allows bromoacetylation of primary amine groups followed by coupling to sulfhydryl-containing compounds. Typically, initial reaction couples via ester to primary amine by amide bond formation in the pH range 6.5-8.5. The second reaction results in thioether bonding in pH range 7.0-8.0.

Caution

The bromoacetyl group is light sensitive.

Synthetic peptides derived from human fibrin were unidirectionally conjugated to three carrier proteins (bovine serum albumin, bovine alpha-lactalbumin, and keyhole limpet hemocyanin) by a method that employs N-succinimidyl bromoacetate. This heterobifunctional crosslinking reagent was prepared with a 79% yield in

A method described here for conjugating synthetic peptides to carrier proteins provides a convenient method for determining peptide-to-carrier protein ratios. N-Bromoacetyl-containing peptides are reacted in situ with carrier proteins in which the disulfide bonds were reduced with tri-n-butylphosphine. At pH
