Antibody (Ab)
Antigens are foreign proteins that your immune system can recognize as being harmful to your body, so it produces antibodies that memorize the antigen protein so it can launch an immune response if it ever again invades your body.
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
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.
antigen-a toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.Antibodies-a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
soluble antigens whch entrs our body
yes..
Antibodies.
Antibodies are produced in response to antigens. If you get infected with one of the 200 viruses that cause colds, these viruses are antigens and your body will respond by making antibodies. The antibodies will inactivate the virus. It usually takes 7-10 for the process to be complete.
Antigen is usually a 'Foreign' protein, usually a microorganism enered in body. It iduces two types of response 1) Cell mediated. 2) Humeral or antibody response. It starts getting produced by 'B' cell in bone marrow. It starts appearing after about 2 weeks of challenge. It give a pick response between 1 to 2 months. It can be inhanced by reapeated challenge during this period. Third challenge or vaccine given at 6 to 9 months, respectively, gives enhanced antibody response. These antibodies are very specific in nature that it will neutralise that perticular protein only. It make the protein inactive. There by protecting body from that perticular protein.
