Application

PrinciplePCR is an in vitro method for enzymatically synthesizing defined sequences of DNA. The reaction uses two oligonucleotide primers that hybridize to opposite strands and flank the target DNA sequence to be amplified. A repetitive series of cycles involving template denaturation, primer annealing, and extension of the annealed primers by DNA polymerase results in the accumulation of a specific DNA fragment, the termini of which are defined by the 5′-ends of the primers.Because the primer extension products synthesized in a given cycle can serve as a template in the next cycle, the number of target DNA copies approximately doubles every cycle; thus, 20 cycles of PCR yield about a million copies (220) of the target DNA. Primer elongation is catalyzed by Taq DNA Polymerase, a heat-stable DNA polymerase isolated from the thermophilic eubacterium Thermus aquaticus BM.

The PCR Core Kit is designed to determine individual PCR conditions for all basic PCR applications relying on Taq DNA Polymerase. Assays which might give better sensitivity and specificity with a non-standard Mg-concentration in the reaction buffer can be optimized using the Mg-free buffer supplied with this kit.

General description

The PCR Core Kit supplies all reagents (polymerase, buffers, dNTPs, etc.) for optimizing conventional PCRs of a specific template with maximum sensitivity, and specifcity. For convenience, each reagent component in the kit is supplied in a separate vial. This allows the user to easily change the amount of polymerase, dNTPs, and MgCl₂ in the reaction mix. Most importantly, the kit allows easy optimization of the Mg²⁺ concentration, one of the most crucial variables in the PCR.
