Descrizione generale

KAPA Taq DNA Polymerase is a single-subunit Taq DNA polymerase from the thermophilic bacterium Thermus aquaticus, purified from recombinant Escherichia coli. KAPA Taq ReadyMix (2X) is a ready-to-use cocktail containing all components for PCR, except primers and template. KAPA Taq ReadyMix is available with and without dye. The 2X ReadyMix with dye consists of two inert tracking dyes to permit direct loading of PCR products onto agarose gels for analysis by electrophoresis, without adding a DNA loading solution. 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.

Applicazioni

KAPA Taq ReadyMix with dye has been used in:
  • high throughput PCR
  • the amplification of low copy DNA templates
  • multiplex PCR
  • specific amplification of complex templates
  • RT-PCR
  • nested PCR (nPCR)
  • amplifying exome 23 of anaplastic lymphoma kinase (ALK)
  • polymerase chain reaction (PCR) amplification

Azioni biochim/fisiol

KAPA Taq DNA Polymerase has 5′→3′ polymerase and 5′→3′ exonuclease activity. It does not elicit a 3′→5′ exonuclease (proofreading) activity. This enzyme system has an error rate of approximately 1 error per 2.2 X 105 nucleotides incorporated. PCR products created with KAPA Taq are A-tailed and are appropriate for cloning into TA cloning vectors.

Caratteristiche e vantaggi

Key Features:
High performance:

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

Quick Notes:
  • KAPA Taq ReadyMix can replace any commercial Taq DNA polymerase in an existing protocol. The annealing temperature may need to be optimized to account for differences in formulation.
  • 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.
  • The 2X KAPA Taq ReadyMix with dye includes two inert tracking dyes, which allow loading of PCR products directly onto agarose gels for analysis.
  • KAPA Taq ReadyMixes contain 1.5 mM MgCl2 and 0.2 mM of each dNTP (at 1X).

Qualità

Each batch of KAPA Taq DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230 Assay). KAPA Taq ReadyMixes 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.

Nota sulla preparazione

Handling:
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.
