Additional Information

The resulting sulfhydryl is available for use in subsequent reactions after exposure to Hydroxylamine. After this deprotection step is performed to create the thioacetylated peptide, the free sulfhydryl containing peptide can then be conjugated to make a hapten-carrier conjugate, polymer, etc.
