Why the B antibody on donor blood group A does not atack the A antigen of the AB recipient?
Jyotiprakashsah91181
Although you donate all of your blood components, only the red cells are given to someone who doesn't have your exact blood type.
B type whole blood will only be given to B. An AB recipient will only get red cells and no plasma so the antibodies in the plasma can not attack the antigens on the red blood cell surface.

Which part of a virus to White blood cells lock onto?
antibody or antigen
What is meant by unexpected antibody in human blood?
An unexpected antibody in human blood means that a person does not have the antigen required to make a certain antibody because it is foreign to them. Unexpected antibodies are usually alloantibodies.
Describe the antibody antigen interactions that would occur if an Rh- perosn with type B blood received blood from an Rh person with type AB blood?
The recipient's antibodies would attack the A and Rh antigens. The body would not benefit at all from the transfusion.
Antigens on red blood cells?
Type A blood has the A antigen and the Antibody anti- B Type B blood has the B antigen and the Antibody anti-a Type AB has antigens AB Type O blood has no antigens, and both the antibodies anti-a and anti-b AB is the universal receiver and O is the universal donor.
How is simulated blood typing activity similar to actual human blood typing?
In both simulated and actual human blood typing, there is an antigen-antibody reaction. A simulated agglutination reaction shows up the antigen.
Why the A antibody of the AB recipient does not atack the donor A antigen on blood?
Having AB blood means you already have both A and B antigens in your organisms, so you DON'T have the antibodies, the A antigen doesn't affect the AB recipient 'cause it doesn't consider it as foreign (it's the same for the B antigen)
What blood has antigen but without antibody?
Surface antigen
If the anti-A antibody causes blood to coagulate which antigen would be present on the red blood cells?
a
What happence when an antigen on a red blood cell comes in contact with the antibody designed to seek it out?
The antibody is killed off, and the antigen spreads
What is formed in the blood to fight invading antigens?
Antibody is a protein made in response to a specific antigen. The antibody attaches to the antigen and makes it useless.
Blood test to identify antigen-antibody reactions?
IMMUNOGLOBULINS
Sperm is not antigen why?
The reason why sperm is not an antigen is because it does not stimulate antibody production. An antigen typically occurs in blood plasma.
What is the Uses of antigen and antibody reaction?
The uses of antigen and antibody reaction will vary but are common for laboratory diagnostics. They are used to test blood compatibility through serological tests.
What antibodies and antigens are in type A plus blood?
Basically, Group A Rh (D) +ve blood type has antigen A and antibody B
Why can type O blood be donated to anyone?
It contains neither A antigen nor B antigen. their blood can be given to individuals of any other blood group red cells do not carry either A or B antigen and hence they do not react with their corresponding antibodies. Remember that an immune respond can only be trigger when the antigen is present in the blood. In another word the blood originally have no any antibody but upon antigen contact it will trigger the immune respond thus antibody is produced and agglutination of blood occur. for rhesus factor there are memory cell so the antibody is still present. That is why when an O blood group without any antigen and antibody (it have both antibody but it is not create yet as there is nothing to trigger its immune respond) can donate to AB group which has no antibody (which mean it will not be trigger by any blood group) but have both antigen (remember that all donated blood have no antibody as there is no immune respond to trigger it thus the AB blood with both antigen is fine; except rhesus factor if it have memory cell)
What is precipitin?
Precipitin-- An antibody in blood that combines with an antigen to form a solid that separates from the rest of the blood
What is the blood component filtered out by the spleen?
the aged red blood cells and antigen-antibody complex
