Application

Maleimide-activated BSA (mBSA) has reactive maleimide groups on its surface available for conjugation with a cysteine-containing peptide or a thiol-containing hapten. The reaction of the maleimide group and the thiol group proceeds rapidly and selectively under mild coupling conditions (pH 6.5-7.5) to yield a stable, covalently linked peptide-protein conjugate that may be used in immunization protocols or in antibody screening methods.

Maleimide Activated BSA has been used in peptide conjugation.

General description

Maleimide Activated BSA is provided in lyophilized, ready to-use form, eliminating the need for time-consuming activation and purification steps of the carrier protein. Maleimide Activated BSA contains approximately 5-15 maleimide groups for each BSA molecule.. The conjugation reaction with a cysteine containing peptide is performed at pH 6.6-7.0. The extent of conjugation can then be determined by a colorimetric assay with Ellman′s reagent) to detect unreacted thiol groups in the cysteine-containing peptide.

Physical form

Each vial contains 5 mg of Maleimide Activated BSA lyophilized from 10 mM sodium phosphate buffer, pH 6.6, with 0.115 mM NaCl, 1 mM EDTA, and 40 mM sucrose as stabilizer.
