Medical Definition of Isoantigen

1. An antigen which can cause an immune response in genetically distinct individuals from the same species. They exist in alternative (allelic) forms in a species, and thus induce an immune response when one form is transferred (for example by blood transfusion or tissue graft) to members of the same species who lack the antigen. Typical isoantigens are the blood group antigens. See: isoantibody. (20 Jun 2000)
