Biochem/physiol Actions

KAPA Taq PCR Kit, which contains 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′ → 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.

Features and Benefits

High performance: Improved sensitivity, specificity, and yields Novel buffer formulation facilitates specific primer annealing, leading to higher yield of specific productQuick Notes: KAPA Taq DNA Polymerase can replace any commercial Taq DNA polymerase in an existing protocol. The final MgCl₂ concentration may need to be optimized to account for differences in buffer formulation. KAPA Taq Buffers contain MgCl₂ at a final concentration of 1.5 mM. Buffer A is recommended as first approach and for applications requiring high yields. Buffer B is recommended for applications where high sensitivity is required (e.g. when the template is limiting). Both buffers may be evaluated to determine the buffer most suitable for a specific application. The KAPA Taq PCR system is suitable for the amplification of fragments up to 3.5 kb from genomic DNA or 5 kb from less complex targets.
