    Notes: [Auszug] pHLA-1 (Fig. Ib, c) contains a 513-base pair (bp) cDNA insert which corresponds to the COOH-terminal 46 amino acids of an HLA class I heavy chain plus a portion of the 3'-noncoding region of the mRNA3. To make a preliminary estimate of HLA class I gene family size, genomic DNA was isolated from a ...

    Notes: [Auszug] We studied DNA from human lymphoblastoid cell line LCL 721 and mutants of it, 721.45.1 and 721.127 (unpublished), from which one entire haplotype or the other had been physically deleted by ?-irradiation. Most important, however, was the analysis of the mutant 721.144 having an A phenotype that ...

    Notes: Abstract Mutants that had lost expression of alleles of one or more HLA loci were isolated with immunoselection after γ-irradiation of a human lymphoblastoid cell line LCL 721. DNAs from the mutants were digested with restriction endonucleases and analyzed by Southern blotting using probes for class I HLA genes. Eight polymorphic cut sites for HindIII and PvuII were discovered in class I-associated sequences of LCL 721. Losses of specific fragments generated by restriction enzymes could be associated with losses of specific antigenic expressions and it was possible in this way to assign HLA-Al, HLA-A2, and HLA-B8 to specific DNA fragments. Patterns of γ-ray-induced segregations of DNA fragments permitted rough linkage alignment of about 30% of the fragments generated by PvuII. The resultant map showed that there are class I HLA genes on the telomeric side of the HLA-A locus. Restriction enzyme site polymorphisms were also examined in a panel of DNAs isolated from peripheral blood lymphocytes (PBLs) of HLA-typed individuals. This panel of PBL DNA complemented the analysis using the HLA deletion mutants.
