Abstract excerpt
Five polymerase chain reaction (PCR) products which could not be reliably typed by allele-specific oligonucleotide (ASO) probing at the human leukocyte antigen (HLA) DQA1 locus were analyzed by polyacrylamide gel electrophoresis and direct sequencing. The first method revealed the preferential amplification of only one of the two alleles in two cases. Direct sequencing of PCR products allowed unambiguous genetic...
