General description
KAPA Taq is supplied in a 2X ReadyMix™ format. It comprises all the components required for PCR except primers and template. Simply use PCR-grade water to make up the required reaction volume. KAPA Taq DNA Polymerase comprises two reaction buffers (Buffer A and Buffer B) or a single buffer with loading dye. It aids convenient direct analysis of the PCR product by agarose gel electrophoresis after cycling. KAPA Taq Buffer A (and KAPA Taq Buffer with dye) are standard Tris-ammonium sulfate-based buffers. KAPA Taq Buffer B is a Tris-potassium chloride buffer. KAPA Taq DNA Polymerase combines with any standard Taq buffer with a pH of 8.3 or higher.
Application
KAPA Taq PCR Kit may be used in:
- High throughput PCR
- Amplification of low copy DNA templates
- Multiplex PCR
- Specific amplification of complex templates
- RT-PCR
- Polymorphism genotyping
Biochem/physiol Actions
KAPA Taq DNA Polymerase is a single-subunit, wild-type Taq DNA polymerase isolated from the thermophilic bacterium Thermus aquaticus. KAPA Taq and KAPA Taq HotStart DNA Polymerase have 5′→3′ polymerase and 5′→3′ exonuclease activities. It does not have 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 associates with a proprietary antibody and inactivates the enzyme until the first denaturation step. Hence, eliminating spurious amplification products and increasing reaction efficiency and sensitivity.
Features and Benefits
High performance :
Quick Notes :
- Improved sensitivity, specificity and yields
- Novel buffer formulation facilitates specific primer annealing, leading to higher yield of specific product.
Quick 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.
Quality
Each batch of KAPA Taq DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230Assay). KAPA Taq Ready Mixes are subjected to stringent quality control tests, are free of contaminating exo- and endonuclease activity, and meet strict requirements with respect to DNA contamination levels.
Preparation Note
Always ensure that the product has been fully thawed and mixed before use. Reagents may be stored at 4°C for short-term use (up to 1 month). Return to -20°C for long term storage.
