[Development of Novel Genotyping Protocol and Its Application for Genotyping of Alcohol Metabolism-related Genes]. Yakugaku Zasshi. 2019;139(8):1111-1119 Authors: Imai M, Kisoi M, Sakaguchi Y, Yamamura M, Kawai S, Murata S, Ichikawa A, Kinoshita K Abstract A new single nucleotide polymorphisms (SNP) genotyping method has been developed and validated using biological specimens directly as templates for TaqMan PCR without general DNA extraction and purification procedure from dried saliva samples attached on water-soluble papers. This new method can set up at ease and complete PCR analysis including data interpretation in under two hours with additional advantages of application for large-scale clinical research, diagnostics, and epidemiological studies at low cost. Specifically, SNP genotyping of alcohol metabolism-related genes ADH1B (rs1229984) and ALDH2 (rs671) were demonstrated by TaqMan PCR assay using dried saliva samples in the present investigation. In this protocol, by simplifying experimental operations and improving efficiency, omitting and simplifying the time and laborious DNA purification process, it is possible to shorten the experiment time and reduce the risk of human error such as contamination. Furthermore it became possible with great cost reduction. We succeeded in dramatically improving the judgment rate and accuracy of SNP genotyping by the master mix reagent for commercial available real-time TaqMan PCR. Moreov...
