摘要： 目的 探讨唾液酯酶（ Set）多态性在法医学亲权鉴定和个体识别方面的应用价值。方法 应用聚丙烯酰胺凝胶盘状电泳及固蓝 RR染色方法，调查了 114名中国人 Set的表型分布及基因频率，用χ 2检验进行统计学分析。结果 中国人酯酶表型频率 Set F 22.81％， Set FS 50.88％， Set S 26.31％ ;基因频率为 SetF 0.482 5， SetS 0.517 5;非父排除机率为 0.187 5，个体识别率为 0.619 9。结论 Set有较高的父权排除率和个体识别率，可作为法医学亲权鉴定和个体识别的重要标记系统之一。

Abstract: Objective To research the value of polymorphism of salivary esterase(Set)in paternity and personal identification. Methods Phenotype and genotype of human salivary esterase were detected in 114 liquid saliva samples from the Chinese population by disc electrophoresis and fast blue RR staining assay. Results The frequency of Set type was F 22.81％ ,FS 50.88％ ,S 26.31％ .The estimated gene frequency of Set F was 0.482 5 and SetS was 0.517 5.The PE was 0.187 5 and the DP was 0.619 9.Conclusion Polymorphism of salivary esterase (Set) was practical in paternity and personal identification.

Key words: salivary esterase(Set), gene frequency, paternity identification, personal identification
