Opsonins

Opsonin (OPSO) is the property of blood to prevent agglutination of red blood cells due to the formation of protective antigens on their surface. The opsonic index is determined by the difference in the binding of antigens by erythrocytes of homologous and heterologous donors. OPSONIC ABILITY BLOOD. This is the ability of blood plasma to increase the stickiness of red blood cells, and the first drops of blood begin to clot only if they contain opsonin (a protein that can stick to red blood cells). If there are not enough protein molecules on the surface of red blood cells for this, then the coagulation process is delayed and
