Scope Note
Large (>160 kDa) glycoproteins with electrophoretic mobility of ALPHA-GLOBULINS, found in high concentration in the plasma of PREGNANT PEOPLE but also in a number of species including mouse, rat, and others (ALPHA-MACROGLOBULINS). In humans, they are always present in the circulation and are nonspecific inhibitors of PROTEINASES, similar to COMPLEMENT PROTEINS (C3; C4; C5).
