Method and kit for amplification, sequencing and typing of classical hla

Abstract

Amplification primer and sequencing primer sites have been identified which permit sequence-based typing of each of the classical HLA genes in highly robust and consistent reactions without allelic dropout. To determine the DNA sequence, and thus the type of at least one exon of an HLA-A, HLA-B and HLA-C gene present in a sample, the sample is combined with an amplification reaction mixture containing the amplification primers and amplified to form an amplification product including exon 2 and exon 3 of the gene together in a single fragment. The amplification product is then combined with a sequencing reaction mixture containing one or more oligonucleotide sequencing primers which hybridize to a conserved regions the amplification product. The oligonucleotide sequencing primers between them are effective to produce sequencing fragments from all known alleles of exon 2 or exon 3 of the gene under suitable conditions to produce sequencing fragments. The sequencing fragments are then evaluated to determine the sequence of exon 2 or exon 3 of the gene in the sample.
