Immunoglobulin G (IgG) has four domains in its structure: two identical heavy chain domains and two identical light chain domains. Each heavy chain consists of one variable domain (VH) and three constant domains (CH1, CH2, CH3), while each light chain has one variable domain (VL) and one constant domain (CL). This overall structure contributes to its ability to bind antigens effectively.
