Taq Core Kit contains all reagents required for PCR (except template and primer) in one box combining simple handling with high flexibility. The premium quality polymerase, ultrapure dNTPs and the optimized complete reaction buffer ensure superior amplification results. The additional reaction buffer without MgCl2 in combination with the MgCl2 stock solution allows an easy optimization of difficult amplifications.
The kit is recommended for use in routine PCR reactions. It is optimized for high specificity and guarantees minimal by-product formation. The buffer system is recommended for plate based PCR and automated pipetting.
The enzyme replicates DNA at 72 °C. It catalyzes the polymerization of nucleotides into duplex DNA in 5'→3' direction in the presence of magnesium. It also possesses a 5'→3' polymerization-dependent exo-nuclease replacement activity but lacks a 3'→5' exonuclease activity.

Optimization of MgCl2 concentration:
A concentration of 1.5 mM Mg2+ is recommended for most applications. For an individual optimization add MgCl2 stock solution as shown in the table below.

1)The annealing temperature depends on the melting temperature of the primers used.
2)The elongation time depends on the length of the fragments to be amplified. A time of 1 min/kb is recommended.

For optimal specificity and amplification an individual optimization of the recommended parameters may be necessary for each new template DNA and/or primer pair.
