which IgG cannot activate complementIgG4
cell surface marker to distringuish different stages in maturation of T cellsCD3
form of graft involves tissue or organ transplantation between identical twinsisograft/isogenic graft/syngraft
is Antigen/Ab binding irreversible?no, reversible because not linked covalently
