a person having an AB blood grp is a universal recipient, which means it has no antibodies in blood that bounce to a reaction in case of blood transfusion ! but it has WBC which produce antibodies ! where did they go ? why they do not react?

Since people with AB Blood group have both A and B antigens displayed on the surface of their RBCs, they do not produce antibodies to either A or B antigens. So they can accept blood from any blood group, but only as packed RBCs, because whole blood from another non-AB donor would have antibodies to either A or B or both and would attack the persons own RBCs. A peson with blood group O has not antigens displayed on their RBCs and can therefore donate blood (again packed RBCs) to anyone since there are no antigens to recognize.

Transfused blood does not contain a large number of antibody producing plasma cells, as most are located in lymphoid tissue. The antibodies present in the transfused blood for the A or B antigen are not present at high enough levels to cause problems.
If AB donates to an O patient, the antibodies in the O patient will react to the A and B antigens on the donor blood, causing all the problems

You'll find even more on Google, hon.
