| 摘 要： | 根据已经测定的乙脑病毒WHe株全基因组序列(GenBank EF107527),设计1对引物扩增基因组全长cDNA和2对特异性的鉴定引物。经RT-PCR技术扩增后,得到约9 kb的产物,经过反复实验,鉴定为外源性污染核酸扩增产物,并加以有效的排除,初步的研究表明该产物可能是由外源性污染核酸自身反向部分互补扩增所致。

| Abstract: | Two primers used to amplify the full length of Japanese encephalitis virus(JEV) WHe strain and another two pairs of primers used for identification were designed according to the complete genome of JEV-WHe strain(GenBank number,EF107527).A 9 kb cDNA fragment was produced with the long RT-PCR,and it was identified as a non-specific amplification.The research showed that this products was amplified from unknown DNA or RNA templates. |
