Description

General description

KAPA2G Fast DNA Polymerase is a second-generation (2G) enzyme engineered for higher processivity and speed, offering significantly faster extension rates than wild-type Taq polymerase. In addition to speed, KAPA2G Fast provides higher yields and sensitivity than competitor enzymes across a broad range of targets. KAPA2G Fast HotStart^® PCR Kits are designed for fast PCR, in which total reaction times are 20–70% shorter than those of conventional PCR assays performed with wild-type Taq DNA polymerase. This can be achieved without sacrificing reaction performance, and does not require specialized PCR consumables or thermocyclers.

Application

KAPA2G Fast HotStart PCR Kit has been used for:

• Fast PCR
• Genotyping
• The quantification of chromatin immunoprecipitation (ChIP)-seq libraries
• Routine polymerase chain reaction (PCR)

Biochem/physiol Actions

KAPA2G Fast DNA Polymerase generates DNA fragments, which share the same characteristics as DNA fragments generated with wild-type Taq DNA polymerase. It is useful for routine downstream analyses, like restriction enzyme digestion, cloning and sequencing. Similar to wild-type Taq, KAPA2G Fast has 5′→3′ polymerase and 5′→3′ exonuclease activities. But it has no 3′→5′ exonuclease (proofreading) activity. The fidelity of KAPA2G Fast is comparable to wild-type Taq, which has an error rate of approximately 1 error per 1.7 x 10⁵ nucleotides incorporated.

Features and Benefits

Reduce cycling times up to 75% :

• Extension times as low as 1 sec per kilobase
• Broad coverage of both AT- and GC-rich targets

High speed, higher performance :

• Single copy sensitivity from complex targets
• Increased yields

Quick Notes :

• KAPA2G Fast HotStart^® PCR Kits contain the engineered KAPA2G Fast HotStart DNA Polymerase, developed for fast PCR.
• Use 1 sec extension time for amplicons <1 kb and 15 sec/kb for longer amplicons, and save 20–70% of total reaction time.
• No need for specialized instrumentation or PCR consumables.
• Optimized buffer system offers improved yields,specificity and sensitivity, facilitating efficient primer annealing across a wide range of primer lengths,GC contents, and melting temperatures.
• Use 0.5 U KAPA2G Fast HotStart DNA Polymerase per 25 μL reaction, or less for smaller volumes.
• For high reaction efficiency, do not exceed 25 μL reaction volumes.
• The buffer is available with and without MgCl₂ KAPA2G Buffer A contains 1.5 mM MgCl₂ at 1X_, while KAPA2G Buffer M is Mg-free.Aside from MgCl₂ content, these two buffers are identical.
• Reaction products are 3′-dA-tailed and may be cloned into TA cloning vectors.

Quality

Each batch of KAPA2G Fast DNA Polymerase is confirmed to contain <2% contaminating protein (Agilent Protein 230 Assay). KAPA2G Fast ReadyMix^™ is subjected to stringent quality control tests, is free of contaminating exo- and endonuclease activity, and meets strict requirements with respect to DNA contamination levels.

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.

Other Notes

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