摘要

DNA sequences coding for the DR- beta -chain locus of human lymphocyte antigen complex and diagnostic typing processes and products related thereto. DNA sequences that code for the beta -chain DR locus are useful in simple and efficient typing processes and products and for expression of polypeptides displaying an immunological or biological activity of the antigens of the HLA-DR beta -chains for use in diagnostic, preventive and therapeutic agents.
