Abstract

Polyclonal antibodies reactive with a cleavage site in human proinsulin (HPI) (C-peptide-A-chain junction) have been raised (rabbit, guinea pig) using a synthetic peptide antigen coupled with keyhole limpet hemocyanin. These antisera recognize native HPI and des-31,32-HPI equally well but react 20-50 times less well with des-64,65-HPI, the intermediate cleaved at the C-peptide-A-chain junction and lacking the Lys-Arg pair. The guinea pig antisera did not recognize insulin but reacted weakly with C peptide at high concentrations; the rabbit antisera reacted with neither insulin nor C peptide. Immunocytochemical studies with human islet tissue localized the immunoreactivity of these antisera to clathrin-coated (pro)secretory vesicles derived from the trans Golgi, indicating that cleavage of the C-peptide-A-chain junction of proinsulin occurs mainly, if not exclusively, in this compartment of the beta cell.
