Opsonization in immunology

Opsonization is a process which enhance the efficiency of the phagocytic cells and trigger the process of phagocytosis. This process involves specific antimicrobial agents (mainly some proteins like antibodies etc) which are termed as opsonin. Opsonization is one of the vital part of immunology. Opsonin: The biomolecules that binds to the surface of the pathogen …
