  • Polymerase chain reaction - Wikipedia


    In practice, PCR can fail for various reasons, in part due to its sensitivity to contamination causing amplification of spurious DNA products. Because of this, a number of techniques and procedures have been developed for optimizing PCR conditions. Contamination with extraneous DNA is addressed with lab protocols and procedures that separate pre-PCR mixtures from potential DNA contaminants. This usually involves spatial separation of PCR-setup areas from areas for analysis or purification of PCR pr

    28/06/2010  PCR cleanup isn’t a DNA extraction technique per se, but it is worth a mention here. Typically, PCR products are cleaned up by adding 3-5 volumes of salt per volumes of PCR reaction, followed by centrifugation of the mixture through a spin column. Although a failed clean-up is often caused by an unsuccessful PCR, it is worth saving your flow-through after column binding. If a strong PCR
