Procedure: Steps of PCR. The optimal conditions for the concentration of Taq DNA polymerase, template DNA, primers, and MgCl 2 will depend on the system being utilized. It may be necessary to determine the optimal …
WebHowever, a primer should not be too long (> 30-mer primers) or too short. Short primers produce inaccurate, nonspecific DNA amplification product, and long primers result in a … WebA PCR master mix is a batch of PCR or RT-PCR reagents that can be divided among many PCR reaction tubes. It usually includes DNA polymerase, dNTPs, MgCl2 and buffer. Make ... 2× concentrated master mix that contains all the reagents (except primers, probe, and template) needed for running quantitative, real-time DNA-detection assays ...
WebThe Hot Start dNTP Mix is provided as a concentrated 2 μM or 10 μM solution of dATP, dCTP, dGTP and dTTP. The dNTP sets are provided as a 10 μmol solution of each individual dNTP.
