IgG1 is the dominant antibody with high FC receptor affinity
IgG2a and IgG2b are strong complement antibodies (mice, humans only have IgG2)
IgG2c Fc receptor "clean up antibody" only macrophage pick up not complement
IgG3 is seen less often with some viral infections

Disulfide bonds in IgG
IgG1 has 2
IgG2 has 4
IgG3 has 11
why does IgG3 have 11 disulfide bonds? is it because it interacts with DNA?
