A radioimmunoassay has been developed for the N-terminal region of human pituitary pro-opiocortin (N-POC), the common precursor protein of ACTH and beta-LPH, using an antiserum which recognizes residues near the gamma-MSH region. The concentrations of greater than 300 ng/l of immunoreactive peptide were determined in unextracted human plasma, the relative molecular mass of the reacting fragments corresponding to a seventy-seven amino acid glycoprotein. The concentrations of immunoreactive N-POC peptides were correlated with those of ACTH in plasma obtained from patients with various disorders of the hypothalamic-pituitary-adrenal axis.
