Macroprolactin is a physiologically inactive form of prolactin found in a small proportion of people. It is in fact prolactin bound to IgG. Macroprolactin, also conventionally known as “big-big prolactin”, refers to the presence of marked hyperprolactinemia associated with evidence of prolactin-IgG (typically IgG4) circulating complexes displaying a molecular weight of approximately 150 kDa (which is hence 6–7 fold hig… keyboarding typing practiceWebb2 apr. 2012 · Macroprolactin is a complex of immunoglobulin G (IgG) and monomeric PRL with prolonged plasma half-life due to delayed renal clearance.
