Progesterone ELISA Assay

Progesterone (C21H30O2) is a C‐21 steroid hormone which belongs to a class of hormones called progestogen. Progesterone is the major naturally occurring human progestogen, and an essential regulator of human female reproductive function in the uterus, ovary, mammary gland and brain, involving in the female menstrual cycle, gestation and embryogenesis. Progesterone also plays an important role in non‐reproductive tissues such as the cardiovascular system, bone and the central nervous system. For instance, to perform its neurotrophic effects in the peripheral nervous system, Progesterone activates the growth and maturation of axons and stimulates the repair and replacement of myelin sheaths in regenerating nerve fibers. Progesterone action is conveyed by two isoforms of the nuclear Progesterone receptor (PR), PRA and PRB. PRA and B are expressed in a variety of normal breast tissue from humans, rats and mice.
