PCR-DGGE(变性梯度凝胶电泳) 普通的聚丙烯酰胺凝胶电泳只能通过片段大小不同在同一浓度的胶上电泳迁移率不同而分离不同的DNA片段,对于片段大小接近或相同的DNA片段无法做到有效地分离;DGGE(denaturing gradient gel electrophoresis) 即变性梯度凝胶电泳,是利用DNA在不同浓度的变性剂中解链行为的不同而导致电泳迁移率发生...
紫外透射灯下观察DNA条带,确认扩增结果。具体操作可以参考之前写的关于琼脂糖凝胶电泳的文章《实验操作教程|琼脂糖凝胶电泳(Agarose Gel Electrophoresis)》。 四、注意事项 引物设计:引物的特异性、长度、GC含量和Tm值需合理设计,避免形成二聚体或非特异性扩增。 污染控制:避免外源DNA污染,操作时需使用无菌技术。 酶...

Genotyping of Neisseria gonorrhoeae by Pulse Field Gel Electrophoresis and PCRAuxotyping (growth of cells on chemically defined media) and serotyping (reaction of cells with a defined set of monoclonal antibodies [MAbs]) are the traditional and most widely used methods for the classification of ...
Gel electrophoresis Primers Primers are short fragments of DNA or RNA used to start DNA synthesis by a DNA polymerase. They are typically 18-25 nucleotides in length and will bind (anneal) to a complementary region of a single-stranded DNA, called the template strand. They mark the beginning...
Real-time PCR combines PCR amplification and detection into a single step. This eliminates the need to detect products using gel electrophoresis, and more importantly it enables the method to be truly quantitative. With real-time PCR, fluorescent dyes are used to label PCR products du...
