<p>Ig - Antibodies. Short description:
There are several types of Ig occuring in different places in body, having different features: IgG IgA IgM IgE IgD. It’s function is opsonization [making more eatable for macrophages/neutrophiles and other leukocytes [I do not remember if NK cells have CR1-X sorry. It has just flown off.]] of bacteria and nonspecific lysis of pathogenes.</p>
