What are Opsinins? What are its roles? How does it work?
phagocytic cell must bind to target.
Opsonins - increase contact by coating the target cell. ex. dead neutrophils, antibodies and activated (fixated) complement components. The process is called complement activation and fixation as part of the opsonization.
Inactive complement proteins in the blood are stimulated and becomes active. it joins other activated complement proteins, surrounds an antigen and sticks to the antigen.
