Question

Antisera B yellow colour why.

Answer 1

Answer:

Antisera are used to determine which antigens are on the red cells. The test using antisera and the patient's red cells is called the front cell group. The antisera used in the front group are obtained from plasmapheresis of donors stimulated with soluble antigens (A substance from pig mucosa and B substance from horse mucosa). Alternatively, monoclonal antisera can be prepared from cultured cell lines.
