摘要
为建立鉴定普氏野马的PCR方法,根据线粒体D-Loop区序列,设计了针对普氏野马的特异性扩增引物,通过优化反应体系和扩增条件,建立了能够鉴定普氏野马的PCR方法。该方法检测灵敏度较高,可扩增10-3ng的DNA,与蒙古马、伊犁马、哈萨克马、阿拉伯马、驴、骡、牛和羊等动物均不发生交叉反应,具有很好的特异性。结果表明,建立的普氏野马物种鉴定的PCR方法特异性好,灵敏度较高,简单可靠,可作为普氏野马的一种有效鉴定方法,对普氏野马的保护起到重要的作用。
To develop the species-specific PCR assay for the identification of Equus przewalsrii ,primers were designed from mitochondria D-loop region after alignment of the available sequences in the GenBank database .The primers generated specific fragments of 315 bp length for Equus przewalsrii .The results showed that the PCR was established .The sensitivity analysis showed that the developed PCR could detect 10-3 ng DNA ,and no cross reaction with Mongolia horse ,Ili horse ,Kazakh horse ,Arabian horse ,Don-key ,Mule ,Bovine and Ovine .The results demonstrated that this species-specific PCR provided a useful , specific ,sensitive and simple technique to identify Equus przewalsrii .This assay could play an important role in conservation of Equus p rz ew alsrii .
