“…The alleles of HLA-A, HLA-B, and HLA-DRB1 loci were studied using PCRs followed by hybridization with sequence-specific oligonucleotide probes (SSOPs) as described earlier (48), using a bead-based technology (Luminex, Austin, TX) and following the manufacturer's instructions (LABType SSO kit from One Lambda, Canoga Park, CA, USA). The latest nomenclature for the HLA system was used to designate the alleles of the three loci studied (49). The data acquired were analyzed using LABType software (One Lambda) for analysis of HLA alleles.…”
