Production and characterization of monoclonal antibodies to 17 alpha-hydroxyprogesterone

J Steroid Biochem. 1987 Oct;28(4):405-10. doi: 10.1016/0022-4731(87)91058-2.

Abstract

Hybridoma clones producing antibodies to 17 alpha-hydroxyprogesterone (17-OHP) were established by using a 17-OHP-bovine serum albumin conjugate as an immunogen. Six representative IgG-class monoclonal antibodies of high affinity (10(8)-10(9) M-1) showed differential reactivities with several structurally related steroids. Two enzyme immunoassay (EIA) systems (fluorescence EIA and micro-EIA) for 17-OHP using OHP 4B2.2.3, which showed the lowest cross-reactivity with other steroids, were established. The micro-EIA system was shown to be applicable to the mass-screening of congenital adrenal hyperplasia.
