설명

애플리케이션

KAPA Taq HotStart^® has been used for:

• High throughput PCR
• Amplification of low copy DNA templates
• Multiplex PCR
• Specific amplification of complex templates
• RT-PCR
• confronting two-pair primers-polymerase chain reaction (CTPP-PCR)
• end-point PCR

생화학적/생리학적 작용

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 HotStart 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.

특징 및 장점

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 HotStart^® DNA Polymerase can replace any commercial hotstart Taq DNA polymerase in an existing protocol. The final MgCl₂ concentration and annealing temperature may need to be optimized to account for differences in formulation.
• The KAPA Taq HotStart Buffer is a uniquelyformulated buffer offering improved specificity and sensitivity, and improved amplification of GC- and AT-rich templates.
• The KAPA Taq HotStart Buffer does not contain MgCl₂; MgCl₂ (25 mM) is supplied separately to allow greater flexibility during reaction setup.
• The KAPA Taq HotStart PCR Kit is suitable for the amplification of fragments up to 3.5 kb from genomic DNA or 5 kb from less complex targets.

품질

Each batch of KAPA Taq HotStart^® DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230 Assay). KAPA Taq HotStart PCR kits 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.

제조 메모
