Progesterone ELISA kits are assays designed to detect the steroid hormone progesterone, which is involved in the female reproductive cycle and pregnancy. It is secreted by the corpus luteum and the placenta. It acts on the brain, uterus, mammary glands and is a precursor to aldosterone. It functions as a transcriptional regulator and is important to maintain pregnancy. Progesterone can be taken as a synthetic medication for hormone therapy and for gynecological complications.
