High yields of PCR product are achieved, even after storing TopTaq Master Mix for 4 months at 25C or 4C, demonstrating the fact that TopTaq Master Mix offers a very robust and reliable amplification system (see figure Reliable high-yield PCR). The kit combines a versatile chaotropic buffer with a glass fiber matrix supported in a spin column for the purification of DNA from both solution and agarose gel. Then add 200 l ethanol (96100%), and mix again thoroughly by vortexing. Note: Gel purification is most efficient with lower % agarose gels, so you will want to stay in the 0.7-0.8% range if possible. In general, reduction of the binding buffer volume is possible without a reduction in the DNA recovery rate. Problems with starting template Check the concentration, each PCR cycle doubles the flame of amplicon in the reaction. For purifying DNA in NGS workflows, we use For optimal plasmid preparation conditions, particular attention should be paid to the lysis conditions as described in the protocol.
