1. they determined by precursor substances which acted upon by the H-gene converted to h- substances.
2. they are found on the red blood cell in an in soluble stage.
3. most have molecular weight of 10000.
4.most are proteins, some are polysaccharides,glycoproteins, glycolipids and nucleoproteins.
1-Response is antigen-dependent 2-There is a lag time between exposure and maximal response 3-Antigen-specific 4-Exposure results in immunologic memory
A antigen
Abwehrstoff or Antigen
the antigen must bind to the receptor
Reference ranges for the antigen/antibody tests are as follows: hepatitis A antibody, IgM: Negative, hepatitis B core antibody: Negative, hepatitis B e antibody: Negative, hepatitis B e-antigen: Negative.
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.
An antigen is a protein made in response to a specific antigen.
Surface antigen
Another term for univalent antigen
No.
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.
A soluble antigen is a viral antigen that remains after the virus has been removed. A particulate antigen is produced by particles such as dust and germs.
