Expression of HLA-DR antigens at the surface of mouse L cells co-transfected with cloned human genes

Abstract
The H-2 I region in the mouse and the HLA-D region in humans contain a set of polymorphic genes which encode Ia antigens and control the immune response. Cloned genes for the different polypeptide chains of one of the human Ia antigens, HLA-DR, have been used for the co-transformation of mouse L cells. Expression of HLA-DR antigens at the surface of transfected mouse cells has been documented with monoclonal antibodies.
