Does an antigen cause an allergic reaction?
Only if the person is already allergic to that antigen. Not if they are immune to the antigen. The word antigen refers to the protein that joins with the antibody.

What bind with specific antigens in the antigen-antibody response?
The Fab portion of the antibody is what determines the idiotype. The Fab portion consists of both a heavy and light chain and is connected to the Fc region (isotype). Every B cell will express a different Fab structure and in a single B cell it will produce only the same Fab.
