What is a monovalent antigen?

A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.


What is the part of the antibody that binds to the antigen?

The part of the antibody that binds to the antigen is called the antigen-binding site, which is located at the tips of the Y-shaped structure of the antibody. This site is formed by the variable regions of both the heavy and light chains, allowing it to specifically recognize and bind to a particular antigen. The unique structure of the antigen-binding site is determined by the amino acid sequence, which varies between different antibodies, enabling the immune system to target a wide range of pathogens.

What are the Tumors that are S 100 antigen positive?

Tumors that are S-100 antigen positive include melanoma, schwannoma, and some types of non-melanoma skin cancers. S-100 is a protein marker commonly found in these types of tumors and can be used in their diagnosis and classification.

Which of the following is not an antigen that may be found on the surface of an erythrocyte a A antigen b B antigen c O antigen d Rh antigen?

The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.


What is antigene and antibody?

An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.


What is the protein made in a response to a specific antigen called?

An antigen is a protein made in response to a specific antigen.


Type blood has B antibodies?

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.
