PCR troubleshooting guide to determine the cause of PCR failure and improve PCR efficiency, or use genez™ ORF cloning easily puts the desired gene into the vector you want.
Second, the non-methylation primers are typically AT-rich and thus need to be long (e.g., >30 nt) with Tm≥60°C to enable specific annealing. In addition, high-AT sequences often favor primer-dimer formation, mismatch hybridization, ...

以下有几点建议: 确保引物在3’末端没有互补序列。 试试热启动聚合酶。 通过将退火温度递增2-5℃并最大限度缩短退火时间来优化退火步骤。你可以尝试在前几个循环中使用较高的退火温度,然后在后续的循环中降低退火温度。 针对每种模板...

Usually a dilution with 5 volumes of water should be sufficient to eliminate even larger unwanted primer-dimer fragments while purifying the 164 bp fragment with > 90 %. 8 MACHEREY-NAGEL – 02/2017, Rev. 04 PCR clean-up, gel extraction 1 2 3 4 5 6 7 8 9 10 11 12 [bp/...
Primer dimer.Primer dimer may be occasionally observed if the gene expression level is very low. If this is the case, increasing the template amount may help eliminate the primer dimer formation. Multiple bands on gel or multiple peaks in the melting curve.Agarose gel electrophoresis or melting ...
