  • Patent number: 11939630
    Abstract: Disclosed is a fluorescent PCR method for detecting HLA-B*15:02 allele and a specific primer probe combination. In the present disclosure, a set of primers and probes are designed based on an HLA-B*15:02 specific SNP gene locus by using TaqMan probe technology, combining another set of primers and probes corresponding to the internal reference gene ?-Actin, and a set of primer probe for non-HLA-B*15:02 genes are designed to detect whether a DNA sample contains an HLA-B*15:02 gene and whether a sample is homozygous or heterozygous. Compared with the similar detection methods in the past, the technical scheme in the present disclosure inherits the advantages of high specificity, high throughput, high resolution, low cost, simple and convenient operation, process controllability and the like of the fluorescent PCR, and may detect whether a sample is homozygous or heterozygous.
