应用３ 个 Ｓ Ｔ Ｒ 基因座在同一反应体系中进行互不干扰的多重 Ｐ Ｃ Ｒ， 采用高分辨力的聚丙烯酰胺凝胶电泳分离、银染法显影技术， 对云南哈尼族的 Ｃ Ｓ Ｆ１ Ｐ Ｏ， Ｔ Ｐ Ｏ Ｘ 和 Ｔ Ｈ Ｏ１ 等３ 个基因座等位基因的基因频率进行调查， Ｃ Ｓ Ｆ１ Ｐ Ｏ 基因座， 观察到７ 个等位基因， １７ 个基因型； Ｔ Ｐ Ｏ Ｘ 基因座， 观察到６ 个等位基因，１３ 个基因型； Ｔ Ｈ Ｏ１ 基因座， 观察到６ 个等位基因， １９ 个基因型． 获得了满意的结果， 显示了广阔的应用前景．
Using 3 S T R loci to perform multiple P CRs without interference in the same reaction system, using high-resolution polyacrylamide gel electrophoresis separation and silver staining to develop the technology. The gene frequencies of three locus alleles such as P O, T P O X and T H O1 were investigated. At the C S F1 P O locus, 7 alleles and 17 genotypes were observed; T P O X At the locus, 6 alleles and 13 genotypes were observed; at the T H O1 locus, 6 alleles and 19 genotypes were observed. Satisfactory results have been obtained, showing a broad application prospects.
