Term Description

Prolactin is measured before and after PEG-treatment of the sample. The PEG treatment precipitates the macroprolactin and leaves the monomeric prolactin in the sample (more or less). The monomeric prolactin (prolactin result after PEG-treatment) is divided by the total prolactin (prolactin result before PEG-tratment) and the result multiplied with 100 yielding the percentage of monomeric prolactin.

Part Description

LP68274-7   Prolactin.monomeric
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.
