Abstract
We have constructed cDNA clone libraries from two lymphoblastoid cell lines, JY (HLA-A2, B7, C untypeable) and LB (HLA-A28, B40, Cw3), and isolated clones encoding class I HLA antigens. We have characterized short oligonucleotide probes derived from the coding region of the HLA class I antigens which are specific for the HLA-A and -B loci. These probes have been used to subdivide the class I cDNA clones into subclasses. DNA sequencing of several HLA-A and -B related clones has allowed us to extend the primary structural characterization of these cell-surface antigens. This analysis has also detected a sequence polymorphism at the HLA-A locus, indicating that the previously considered homozygous typing cell line LB expresses two alleles of similar, although not identical, serological specificity.
