A series of sequence-specific oligonucleotides (SSOs) have been used to type alleles at the HLA-DRB1 locus. Genomic DNA was amplified to high copy number by the polymerase chain reaction (PCR) and hybridizations of the dot-blotted, amplified DNA to a series of 14 SSOs enabled the identification of the major specificities DR1-DRw14. Certain alleles (DR3 and DR4) could be rapidly and accurately identified by running the products of allele-specific amplification of genomic DNA on agarose gels. T...Expand abstract
