Description
KAPA Taq DNA Polymerase is based on the single-subunit, wild-type Taq DNA polymerase of the thermophilic bacterium Thermus aquaticus. KAPA Taq and KAPA Taq HotStart DNA Polymerase have 5'-3' polymerase and 5'-3' exonuclease activities, but no 3' to 5' exonuclease (proofreading) activity. The enzyme has an error rate of approximately 1 error per 2.2 x 105 nucleotides incorporated. In the hot start formulation, the KAPA Taq is combined with a proprietary antibody that inactivates the enzyme until the first denaturation step, eliminating spurious amplification products and increasing reaction efficiency and sensitivity.
KAPA Taq is supplied in a 2X ReadyMix format containing all the components required for PCR except primers and template—simply use PCR-grade water to make up the required reaction volume. KAPA Taq ReadyMix is also available with loading dye reaction buffer, allowing, you to load your PCR product directly onto the agarose gel with no extra steps for adding loading/tracking dye.
Kits include KAPA Taq (or KAPA Taq HotStart) DNA Polymerase (5 U/µL), KAPA Taq Buffer, and MgCl2 (25 mM). Kits are available with and without dNTP Mix (10 mM each). The following reaction buffers are available:
– KAPA Taq Buffer A and B (10X, with 1.5 mM MgCl2 at 1X), supplied with KAPA Taq PCR Kits only
– KAPA Taq Buffer with dye (10X, with 1.5 mM MgCl2 at 1X), supplied with KAPA Taq PCR Kits with dye only
– KAPA Taq HotStart Buffer (5x, Mg-free), supplied with KAPA Taq HotStart PCR Kits only
KAPA Taq HotStart DNA Polymerase is also sold separately. ReadyMix formulations (2X) of KAPA Taq DNA Polymerase are also available. These contain DNA Polymerase, reaction buffer (with and without dye), dNTPs and MgCl2 (at a final concentration of 1.5 mM).
