General description

Progesterone or P4 (pregn-4-ene-3,20-dione) is a female steroid hormone that belongs to the hormones class, progestogens. It is produced by majorly by ovaries, adrenal glands and placenta of humans and other species. Progesterone derived from placenta and corpus luteum is required for the maintenance of pregnancy. Progesterone inhibits the T cell mediated immune response involved in tissue rejection. The progesterone levels in females are low before ovulation and are elevated during the luteal phase. Monoclonal Anti-Progesterone antibody is IgG1 isotype purified from rat cell culture supernatant.
