Polymerase Chain Reaction (PCR).
HLA Class II genotyping defines the antigens of the HLA-DRB1 and DQB1 loci of the Major Histocompatibility Complex found on the short arm of chromosome 6. Using DNA extracted from leukocytes, HLA-DRB1 and DQB1 alleles are amplified via PCR using sequence-specific primers. After amplification, the specific HLA antigens are determined by gel electrophoresis for disease association purposes.
