Abstract
Antisera produced by injection of Pr-β-HCG-TT in rhesus monkeys (
) and goat have been analysed for reactivity with various hormones. All antisera bound
125I-HCG. β-HCG competed with labelled HCG for binding to the sera in all cases. No cross-reactivity
of human placental lactogen (HPL) and human growth hormone (HGH) was seen up to 1μg
quantities per assay tube as gauged by competitive inhibition assays. Human follicle
stimulating hormone (HFSH), human luteinizing hormone (HLH) and human thyroid stimulating
hormone (HTSH) did not compete with 125I-HCG at the normal maximum physiological concentration of these hormones. The concentrations
in radioimmunoassay system at which the competition appears with other hormones have
also been determined.
