HLA-A towards a high-resolution DNA typing.
Sequencing-based typing (SBT) and sequence-specific oligonucleotide probing (PCR-SSOP) are DNA-based typing approaches to identify HLA-A alleles. In this study PCR-SSOP SBT have been evaluated and considered to reach a high-resolution typing. Based upon serological typing, 32 genomic samples were typed by SBT and PCR-SSOP Three main clusters of resolution could be defined. The advantage of the PCR-SSOP approach is the possibility to type numerous samples in a short time. SBT minimizes the number of ambiguous heterozygous combinations and often allows direct detection and identification of new alleles.
