title: Comparison of intradermal pigeon crop-sac bioassay and double antibody radioimmunoassay for rat prolactin.
abstract: On an absolute basis, the intradermal pigeon crop-sac bioassay (PCA) gave results that were 20.5% higher than the radioimmunoassay (RIA) in rat anterior pituitary (AP) preparations. A highly significant correlation (r = 0.87) was obtained between RIA (in microgram) and PCA (in Reece-Turner units) when 58 medium samples obtained by culturing rat APs in vitro were assayed for prolactin (PRL) content.
