title: An automated solid-phase 17 alpha-hydroxyprogesterone ELISA method using a microtitre plate.
abstract: We report an automated ELISA method for the measurement of 17 alpha-hydroxyprogesterone in plasma samples. A rabbit antiserum raised against 17 alpha-hydroxyprogesterone-3-(O-carboxymethyl)oxime-bovine serum albumin is used for the assay and a homologous competitor 17 alpha-hydroxyprogesterone-3-(O-carboxymethyl)oxime-bovine thyroglobulin is coated onto a microtitre plate. A goat anti-rabbit IgG-horse radish peroxidase is used as a probe for this solid-phase assay. The assay exhibits good sensitivity, precision and accuracy. The method is used routinely for the management of patients with congenital adrenal hyperplasia.
