ABSTRACT=An efficient, one pot site-specific conjugation of two cysteine-containing peptides was achieved by use of a maleimide/iodoacetyl bivalent linker. Following the initial ligation step, the linker was converted from an unstable thiosuccinimide to a stable thioether by mild aqueous hydrolysis. This method enables efficient, straightforward peptide conjugation for biochemical and medicinal applications.
