The amount of prolactin found in a specified volume of blood, the fluid that circulates through the heart, arteries, capillaries and veins carrying nutrients and oxygen to the body tissues and metabolites away from them. Prolactin is a peptide hormone which is secreted by the anterior pituitary and is involved in lactation, growth regulation for tissues including cells of the immune system, and possibly supression of apoptosis. A peptide hormone is a complex organic compound that contains carbon, hydrogen, oxygen, nitrogen, and sulfur consisting of alpha-amino acids joined by peptide linkages, and that is produced in one part or organ of the body and initiates or regulates the activity of an organ or a group of cells in another part of the body.
