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.
No, type A blood does not have B antibodies.
Type A blood will produce antibodies against B antigens.
A - blood type
Since that person has anti-B antibodies, then A antigens are present in her red blood cells. Since that person doesnt have anti-A antibodies, then there are no B antigens present, which means the person has A type blood.
Individuals with blood type A positive have antibodies against blood type B antigens. This means their immune system reacts against blood from individuals with blood type B if they were to receive a transfusion containing type B blood.
A person with A negative blood will form antibodies to Rh + and to B
Antibodies. They are designed to resist, or fight, specific types of antigens. Type AB has no antibodies, which is why they can receive any type of blood. Type A has B antibodies, which means it will fight type B blood as well as type AB. Type B has A antibodies, which means it will fight type A blood, as well as type AB. Type O has A and B antibodies, which is why it can only receive type O blood.
B+ here is a guide for you: type A - A antigens B antibodies; type B - B antigens A antibodies; Type AB - A&B antigens and no antibodies; type O - no antigens and A&B antibodies. for the rh you just have to add if it is + or -.
Blood type B negative has antibodies against blood type A antigens. This means that individuals with blood type B negative should not receive blood transfusions with type A or AB blood since their immune system will recognize these blood types as foreign and mount an immune response against them.
true
1-Type A ... which has antibodies : B ... and Antigene : A2-Type B ... which has antibodies : A ... and Antigen : B3-Type AB . which has No antibodies ... and has Antigen : A and B4-Type O .. which has antibodies : A and B ... and has No Antigensfrom this information's, you can notice that AB blood type doesn't have Antibodies that's why it accept all types during blood transfusion, when there is no antibodies this means that the body will not consider the other blood types as foreigners.
Individuals with blood type AB have both A and B antibodies present in their blood.
