No, type B blood does not have A antigens. Type B blood has B antigens.
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
If you have the genotype BO, you will have blood type B. This means you will produce B antigens. You will also produce Anti-A antibodies, meaning you cannot receive a transfusion of type A or AB blood.
Type AB blood contains both A and B antigens. This allows the person to receive blood from types A, B, O, and AB.
That would be extremely useful if it can be developed. There are four types of blood: AB, A, B, and O. They are classifed by the antigens that they have. Type O blood has no antigens but it does have anti-A and anti-B antibodies, so it can only accept type O blood (although since it has no antigens, it can give blood to anyone). Type A blood has A antigens and anti-B antibodies so it can't accept any blood with B antigens in it (such as type B or AB). Type B blood has anti-A antibodies and can't accept A or AB blood. Type AB has A antigens and B antigens so it can't donate to any other blood besides AB (although it can receive any type of blood). If everyone was type O blood, and didn't have any antigens, then every type of blood would be able to receive it because the antibodies wouldn't have any antigens to react with so it would be accepted by anyone.
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.
Type AB blood has no antibodies, so people with this blood type can receive blood from A, B, AB, and O types,
A can donate to A because they are the same type. To donate from an A to an AB requires a little more effort. Every person's blood, except for AB blood has antigens which mark blood with "additional letters" as foreign, prompting their destruction. For example, type A blood will have anti-B antigens, type B blood will have anti-A antigens, and type O blood will have both anti-As and anti-Bs. However, AB blood has neither because it has both A and B. However, if blood from an A was put directly into an AB person, the anti-B antigens would begin to attack the AB's native blood, which would cause a number of problems. Therefore, the A blood must first be cleaned of antigens before being able to be donated. A cannot donate to O or B because those people have anti-A antigens in their bloodstream and would just keep making it (even if you found a way to remove all of their current anti-A antigens). This would lead to the body attacking the new blood as opposed to using it.
blood type A has type A antigens. blood type B has type B antigens.
No antigens.That is why they are the universal donors and anyone can receive their blood.
Blood type O can only receive from other blood type Os, because of reactions to the A and B antigens from Blood Type A, Blood Type B and Blood Type AB.
Previous answer: 0 blood type has no antigens.My improved answer: the Bombay phenotype has no antigens.O blood group has H antigens (but does not have A or B antigens), whereas in the Bombay phenotype blood group, even the H antigens are absent.Glenn LowNUS Life Sciences Studentsimmune system
