Macroprolactin/Prolactin [Pure mass fraction] in Serum or Plasma
Active
Term Description
Because of the confusion that occurs in countries that report results as both decimal fraction and percent, this property was created to represent decimal fractions that are reported without units.
Part Description
LP34987-5 Macroprolactin
Monomeric prolactin is the most common form of circulating prolactin. Prolactin also has several isoforms, including the dimeric form ("big-prolactin") that has a molecular weight of ~50 kD and polymeric form ("big-big prolactin") that has a molecular weight of ~ 150 kD). Big-big prolactin, known as macroprolactin, and big prolactin are formed in the circulation after secretion of prolactin from the pituitary. They have a longer half-life than monomeric prolactin are not biologically active. However, typical prolactin assays do not differentiate between the different forms of prolactin, and the presence of big and big-big prolactin can lead to a false diagnosis of hyperprolactinemia. Methods such as PEG precipitation can separate macroprolactin and big prolactin from monomeric prolactin in order to obtain a more accurate measurement of biologically active prolactin, and chromatography can be used to further characterize the isoforms if necessary.
