If a transfusion is needed, blood type has to be determined so that the type in the patient is the same as the blood that will be given.
There are two different types of agglutinogens, type "A" and type "B" on the surface of our red blood cells. Each type has different properties.
The ABO blood type classification system uses the presence or absence of these molecules to categorize blood into four types.
If person has type B on their cells, they will have antibodies in their blood for type A. If this person is given type A, the antigens and antibodies will react causing the blood to clot causing damage and most likely death.
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.
When your body is introduced to the Hepatitis B virus, the virus is considered the antigen (the surface antigen)and this should trigger your immune system to develop antibody against this antigen to destroy it. Most people do develop Hep B surface antibody when infected with the Hep B virus. Some people do not develop the antibodyand go on to have only circulating Hep B surface antigen - which means they are a carrier and can continue to have the virus and infection. For the majority of the population that develop the Hep B surface antibody, this conveys immunity to the virus for life.
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.
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.
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.
antigen a and b and they have no antibodies.
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
Australia Antigen is just a strain of Hepatitis B.
Selectogen I tests for IgG antibodies to hepatitis A virus, hepatitis B virus core antigen, and hepatitis B surface antigen. Selectogen II tests for IgG antibodies to hepatitis C virus, hepatitis B core antigen, and hepatitis B surface antigen.
no answer
blood type A have antigen A and anti body B blood type B have antigen B and anti body A blood type AB have antigens A and B and do not have anti body blood type O do not have antigen but have anti bodies A and B
b
