คำอธิบาย

General description

The second-generation KAPA2G Robust DNA Polymerase evolves to solve inconsistent amplification across a broad range of amplicon types (GC- and AT-rich). This product enables higher processivity and specific activity, which translates to robust PCR performance, high sensitivity, and improved tolerance to common inhibitors. The high performance of the KAPA2G Robust DNA Polymerase is ideally suited for challenging PCR applications and difficult samples, eliminating the need for optimization using multiple enzymes and protocols.

Application

KAPA2G Robust HotStart^® PCR Kit has been used for:

• Amplification of GC- or AT-rich templates
• Templates containing common PCR inhibitors e.g. salts, urea, SDS, or ethanol
• Crude sample PCR e.g. buccal swabs, cultured mammalian, yeast, or bacterial cells
• Colony PCR
• qPCR
• Nested polymerase chain reaction (PCR) amplification
• Amplification of DNA targets in PCR
• DNA amplification using conventional PCR
• Routine PCR

Biochem/physiol Actions

DNA fragments created with KAPA2G Robust HotStart^® DNA Polymerase have the same characteristics as DNA fragments generated with wild-type Taq DNA polymerase. It can be used for routine downstream applications, such as restriction enzyme digestion, cloning, and sequencing. Like wild-type Taq, KAPA2G Robust HotStart has 5′→3′ polymerase and 5′→3′ exonuclease activities, devoid of 3′→5′ exonuclease (proofreading) activity. The fidelity of KAPA2G Robust HotStart is similar to wild-type Taq. It shows an error rate of approximately 1 error per 1.7 x 10⁵ nucleotides incorporated.

Features and Benefits

Efficient amplification of GC- and AT-rich targets

• Robust performance across a wide range of GC- and AT-rich templates
• Increased PCR success rates

Improved tolerance to common PCR inhibitors

• Efficient amplification from crude samples
• Higher yield and sensitivity per unit of enzyme

Unrivalled performance in colony PCR

• Higher yields and improved consistency of PCR direct from E. coli and yeast cells

Quick Notes:

• KAPA2G Robust HotStart^® PCR Kits with dNTPs contain KAPA2G Robust HotStart DNA Polymerase, engineered for high processivity and inhibitor tolerance.
• Both purified genomic DNA and crude samples (e.g. colony PCR) can be used as template.
• Use 0.5 U of KAPA2G Robust HotStart DNA Polymerase per 25 μL reaction. More challenging PCRs (GCrich,crude sample) may require higher enzyme concentrations.
• Use 15 sec/kb extension time per cycle, and increase to 30-60 sec/kb for difficult amplicons or templates.
• KAPA2G Buffers contain 1.5 mM MgCl₂ at 1X.
• Additional MgCl₂ may be added using the 25 mM MgCl₂ solution provided in the kit.
• KAPA2G Buffer A is optimized for high yield, specificity, and sensitivity.
• KAPA2G Buffer B is recommended for inhibitorcontaminated template samples.
• KAPA2G GC Buffer is recommended for GC-rich PCR (>70% GC).
• KAPA Enhancer 1 can be used with KAPA2G Buffer A or B, particularly for GC-rich assays.
• Reaction products are 3′-dA-tailed and may be cloned into TA cloning vectors.

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. Provided that all components have been handled carefully and not contaminated, the kit is not expected to be compromised if left (unintentionally) at room temperature for a short period of time (up to 3 days). Long-term storage at room temperature and 4°C is not recommended. Please note that reagents stored at temperatures above -20°C are more prone to degradation when contaminated during use, and therefore storage at such temperatures is at the user′s own risk.

Analysis Note

Each batch of KAPA2G Robust HotStart^® DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230 Assay). KAPA2G Robust 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.
