each lymphocyte must become able (competent) to recognize its one specific antigen bye binding to it. this ability is called immunocompetence.
Plasma Cell initiate attacks against specific antigens. Plasma cells are B cells bearing specific antibodies for binding to a specific antigen.
Antigen binding is a region on an antibody that binds to antigens. Antigen binding is composed of one constant and one variable domain of each of the heavy and the light chain, and these domains shape the antigen binding site at the amino terminal end of the monomer.
The antigen is the foreign "invader" in the body. The antibody is a tiny "Y" shaped protein that is chemically attracted to a specific antigen; binding to it and thereby marking it for destruction by a white blood cell.
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.
Antibodies bind the antigen, which then targets the antigen for elimination by innate mechanisms
neutralization of the antigen, agglutination or precipitation, and complement activation.
Has no antigen in many textbooks it will state "no A-antigen and no B-antigen"(which imply the possibility of some other antigen) and some will even say, "no antigen" (which is true; antigens are things that attach to antigen binding sites, thus, if it does not fit any antigen binding sites, it is technically not a antigen but merely a "enzyme/protein") but this is just to reduce unnecessary and irrelevant information; they are only concerned about A-antibody, B-antibody, A-antigen, and B-antigen. Nonetheless, know that there are in fact antigens on o blood cells, they are just inactive. My guess is, N acetyl glactosamine on A antigen and Galactose on B antigens are Epitopes (: a small specific regions on antigens that are bound by the antigen receptors on lymphocytes and by secreted antibodies.) Antigens without epitopes will not be detected by antigen binding sites.

Imunocompetent
Polyclonal antibody
Yes. An antigen is a substance that stimulates an animal in order to produce an antibody reaction to counteract the substance by a specific binding antibody-antigen. Most of the times this antigen is a molecule of protein.
