Abstract

HLA-DP genotyping was performed using dot-blot analysis with synthetic oligonucleotide probes. Fourteen probes were designed based on the known sequence variations in the polymorphic segments of the DPβ second exon. Each probe was tested against genomic DNA amplified by the polymerase chain reaction, using DPβ-specific primers. A total of 45 HLA homozygous B-cell lines, selected from the Tenth International Histocompatibility Workshop and pretyped for the known DPw specificities, were analyzed. Different hybridization patterns were found for each DPw specificity. The oligonucleotide hybridization performed on DPw-negative B-cell lines gave a pattern distinct from those of known DPw specificities, indicating the presence of novel DP allelic sequences. The use of sequence-specific oligonucleotides combined with DNA amplification allows a simple and reliable genotyping of DP antigens.
