KAPA2G Robust PCR Kit

The second-generation KAPA2G Robust DNA Polymerase was evolved 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.

KAPA2G Robust PCR Kit is suitable 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
• Polymerase chain reaction

KAPA2G Robust DNA polymerase has 5′→3′ polymerase and 5′→3′ exonuclease activities, but no 3′→5′ exonuclease (proofreading) activity. The fidelity of KAPA2G Robust is similar to that of wild-type Taq; it has an error rate of approximately 1 error per 1.7 x 105 nucleotides incorporated. KAPA2G Robust is a highly processive DNA polymerase, capable of amplifying DNA fragments of up to 1 kb in size with a 15 sec/cycle extension time. The use of excessive extension times is likely to result in smearing and nonspecific amplification. For amplicons <1 kb with genomic DNA as a template, 15 sec per cycle should be sufficient for a high yield of the product. In the case of longer amplicons, the time may be increased to a maximum of 60 sec/kb, in 15-sec increments. PCR products generated by KAPA2G Robust are 3′-dA-tailed and may be cloned into TA cloning vectors.

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.

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