摘要
目的:评估TaqMan-MGB探针基因分型方法检测已知SNP的可行性,并与传统的PCR-RFLP方法比较。方法:高通量的TaqMan-MGB探针基因分型方法已被用来检测单核苷酸多态性(SNP)。在321例样本中,同时用TaqMan-MGB探针基因分型方法和PCR-RFLP方法检测GSTP1外显子5 SNP。结果:2种方法所得结果完全一致。野生型(AA)226例(70.4%),杂合子(AG)92例(28.7%),纯合突变型3例(0.9%)。结论:TaqMan-MGB探针基因分型方法是一种能快速、高度特异性、高度自动化检测SNP的方法,可用于大规模的基因分型。
Objective: To evaluate TaqMan-MGB Probes genotyping method feasibility in detecting a well-known SNP, compared with PCR-RFLP. Methods: A high-throughput genotyping method has been developed to detect single-nucleotide polymorphisms (SNP). In 321 specimens, GSTP1 exon 5 SNP was analyzed by TaqMan-MGB probes genotyping and PGR-RFLP method. Results: The results of the two methods were completely identical: 226 (70.4%) of homozygous wild-type (A.A), 92 (28.7%), heterozygote (AG) and 3 (0.90/0) ,homozygous mutant (GG). Conclusion: Genotyping method of TaqMan-MGB Probes is a rapid method, with high specificity, to highly automatically detect SNP,which can be applied to the large-scale genotyping.
