title: A rapid, flow-through column radioimmunoassay for human chorionic somatomammotropin.
abstract: A rapid, flow-through, column, nonequilibrium radioimmunoassay for human chorionic somatomammotropin (HCS) is described. The total incubation time is about 1 hour, and no centrifugation is needed. Reproducibility, sensitivity, specificity, recovery, and parallelism are adequate for clinical utility. Hormone levels in a variety of pregnancy sera assayed by this column method are closely related to results from another more conventional radioimmunoassay method.
