How does an antigen-antibody response work

WebAntibodies can bind to antigens directly. The antigen must effectively bind with a naive B cell’s membrane-bound antibody in order to set off differentiation, or the process of becoming one of the new forms of a B cell. Memory B cells express the same membrane-bound antibody as the original naive B cell, or the “parent B cell”.
