- 根据设计的引物的熔解温度(Tm)、GC 含量、长度等信息,选择一对最适合的引物。 - 注意避免选择可能会形成二聚体、发夹结构或其他非特异性扩增产物的引物。 - 确保选择的引物能够在预期的 PCR 条件下高效地扩增目标区域。 --- 7. 导出引物序列 在确认选择了最佳引物后,可以将引物序列复制到文本文件中,或记录...
Try to make the melting temperature (Tm) of the primers between 65°C and 75°C, and within 5°C of each other. If the Tmof your primer is very low, try to find a sequence with more GC content, or extend the length of the primer a little...

GC content, melting temperature and annealing temperature are strictly dependent on one another (Rychlik et al., 1990). GC% is an important characteristic of DNA and provides information about the strength of annealing. A GC of 50-60% is recommended. The value recommended by Dieffenbach (1993)...
GC含量:引物的GC含量(即鸟嘌呤和胞嘧啶的含量)应该适中,以确保其在PCR过程中的稳定性和扩增效率。 熔解温度:熔解温度是指引物与目标序列完全结合的温度。通过调整引物的序列和长度,我们可以控制其熔解温度,从而优化PCR扩增的效果。 希望这样解释能让你对primer(引物)有更深入的理解!如果你还有其他问题或者想继续探讨...

GC content is between 45% and 55%. Does not form stable hairpins. Does not self dimerize. Does not cross dimerize with other primers in the reaction. Has a GC clamp at the 3' end of the primer. This example uses MATLAB® and Bioinformatics Toolbox to find PCR primers for the huma...
GC-content: GC-content is the fractionfGCof base pairs in the primer sequence equal to either G (guanine) or C (cytosine). The score term is 1 if 0.5 ≤ fGC ≤ 0.7, 0 iffGC>0.7 orfGC<0.4 and (0.5- fGC)/0.1 if 0.4 ≤ fGC<0.5. ...
4. GC Content: The GC content (the number of G's and C's in the primer as a percentage of the total bases) of primer should be 40-60%.5. GC Clamp: The presence of G or C bases within the last five bases from the 3' end of primers (GC clamp) helps promote specific binding...
