  1. 减少非特异性扩增产物及引物二聚体的生成,提高检测的专一性。

    It enhances the specificity of detection due to decreasing the products from non-Specific amplification and primer dimerization .

  2. 经熔解曲线分析,其扩增产物中未检出非特异性产物和引物二聚体;

    A melting curve analysis shows that , the quantity of unspecific PCR products have witch fewer primer dimers than other amplification products .

  3. 如图6和7所示分别为Ⅰ、Ⅲ胶原的扩增、溶解曲线和溶解峰,说明Ⅰ、Ⅲ胶原是特异性基因表达,无引物二聚体及非特异性扩增。

    As shown in Figure 6 and 7 , respectively ⅰ,ⅲ collagen in the amplification curve and dissolution peaks , indicating ⅰ,ⅲ collagen is a specific gene expression , no primer-dimers and nonspecific amplification .

  4. 结论1.所设计的通用引物能够一次对所研究的七种病原菌进行扩增,且条带结果清晰,未见明显的非特异性条带和引物二聚体。

    Universal primers could successfully amplify seven kinds of pathogens without obvious non-specific amplification or dimers . 2 .
