Taq Core Kit / high yield 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 efficiency and gives best results in a broad range of reaction conditions with most primer-template pairs. The buffer system facilitates the incorporation of labeled or modified nucleotides into DNA. Note that the ammonium based buffer system contains detergent and is not 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.

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.
