摘要: 目的 应用逆转录酶活性检测方法对金黄仓鼠及其它动物血清、细胞进行检测。方法 根据雀麦草花叶病毒RNA序列设计一对引物,加入样品对RNA进行逆转录PCR,电泳观察有无特异条带以确定样品中是否含有逆转录酶。结果 在兔、豚鼠、大鼠以及仓鼠血清中检出逆转录酶活性阳性样本。结论 该方法具有良好的敏感性和特异性,可以应用于动物血清中逆转录酶活性的检测。

Abstract: Objective To detect the reverse transcriptase (RTase) activity in the serum of golden hamster, rabbit, guinea pig, rat, mouse, simian and in Vero, BHK21, PERV cell on the basis of RTase assay. Method A pair of primer is designed according to the BMV RNA sequence. As reverse transcriptase, the serum and cells are tested by reverse transcript PCR (RT-PCR), and the specific band is observed by electrophoresis. Results The RTase activity is positive in rabbit, guinea pig, rat and golden hamster serum. Conclusion This assay has fine specificity and sensitivity, and it can be used in detection for RTase activity in animal serum.

Key words: Hamster, Reverse transcriptase activity, RT-PCR
