半岛bd体育手机客户端 说明

一般描述

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.

应用

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

生化/生理作用

KAPA Taq DNA Polymerase is a single-subunit, wild-typeTaqDNA polymerase isolated from the thermophilic bacteriumThermus 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 105nucleotides 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.

特点和优势

High performance :

  • Improved sensitivity, specificity and yields
  • Novel buffer formulation facilitates specific primer annealing, leading to higher yield of specific product.

Quick Notes :
  • KAPATaqDNA Polymerase can replace any commercialTaqDNA polymerase in an existing protocol.
  • The final MgCl2concentration may need to be optimized to account for differences in buffer formulation.
  • KAPATaqBuffers contain MgCl2at 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 KAPATaqPCR system is suitable for the amplification of fragments up to 3.5 kb from genomic DNA or 5 kb from less complex targets.

质量

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.

制备说明

Always ensure that the product has been fully thawed and mixed before use. Reagents may be stored at 4℃ for short-term use (up to 1 month). Return to -20℃ for long term storage.

其他说明

For Research Use Only. Not for use in diagnostic procedures.
