IgG
#boundingbox
Main antibody in 2° response to an antigen. Most abundant isotype in serum. Fixes complement, opsonizes bacteria, neutralizes bacterial toxins and viruses. Only isotype that crosses the placenta (provides infants with passive immunity that starts to wane after birth). “IgG Greets the Growing fetus.” Associated with warm autoimmune hemolytic anemia (“warm weather is Great”).
