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.
Specific molecules that are recognized by the body as foreign and to which antibodies bind are called antigens. Antigens can be proteins, carbohydrates, lipids, or nucleic acids that stimulate an immune response when they enter the body.
Antibodies are proteins produced by the immune system in response to antigens, which are foreign substances that trigger an immune response. Antibodies bind to antigens to help neutralize or eliminate them from the body, playing a crucial role in the immune response.
An antibody can typically bind to one specific type of antigen.
An antibody can typically bind to two antigens at once.
Yes, antibodies can bind to multiple antigens simultaneously.
Antibodies are biomolecules that have a Y-shaped structure. This Y shape allows antibodies to bind to specific antigens, recognizing and neutralizing them as part of the immune response.
The process of immunity is to produce specific antibodies that bind to antigens on the surface of pathogens. =]
Those are known as antigens.
Antibodies.
Yes, B cells have antibodies on their surface that help them recognize and bind to specific antigens.
Let's start with the first phrase: "All immunogens are antigens" Yes, that's true. Immunogens are antigens that CAN ELICIT IMMUNE RESPONSE and percieved as foreign by the body. Remember, anything that is percieved by the body as foreign is an antigen. Period. Now the second phrase: "All antigens are not immunogens" This is also true. There are antigens, percieved by the body as foreign that CANNOT ELICIT IMMUNE RESPONSE. Example of this is Hapten Molecule. It is an antigen that cannot elicit response by itself, unless paired with a larger protein. In summary: Immunogens - form of antigens that can elicit response. Antigens - anything percieved by the body as foreign that can either elicit or not (Hapten molecule) an Immune response.
There are four types of antibodies that aid in immunity. The Lysins bind the antigens therefore causing them to disintegrate. The Agglutinins bind the antigens causing the micro-organisms to clump together. The Antitoxins bind the toxins therefore making them harmless to the body. The Opsonins bind the antigens on the outer surface.
