title: Radioimmunological quantitation of human group-II pepsinogens.
abstract: A solid-phase sandwich radioimmunoassay was developed to quantitate human group-II pepsinogens in plasma. The test detected pepsinogen II in a concentration range of 0.25--64.0 ng/ml using sample volumes of 125 microliter. Purified group I pepsinogens showed no response up to concentrations of 100 microgram/ml. In apparently healthy donors, we observed mean plasma concentrations of 20.3 ng/ml (males) and of 15.5 ng/ml (females).
