It is listed as having over 300 separate functions and is involved in more processes than any other pituitary hormone. PRL is most commonly known for its lactation stimulating effect, but also plays a role in reproductive behavior, homeostasis of electrolytes, growth and development, regulation of metabolism, immune system regulation, angiogenesis, and survival of cancer cells. PRL acts as a ligand for the prolactin receptor, PRLR.Sterile Filtered White lyophilized powder.
