DNA Polymerase High Fidelity (HiFi) Enzyme

DNA Polymerase High Fidelity (HiFi DNA Polymerase) contains T-DNA Polymerase and a proofreading 3'-5' exonuclease. This kit contains two different buffers: HiFi Buffer 1 is optimized for the amplification of genomic DNA, and HiFi Buffer 2 is optimized for the amplification of λDNA, cDNA or plasmid DNA. The extension rate is about 1-2 kb/min. Template-independent "A" can be generated at the 3' end of the PCR product. PCR products can be directly cloned into T-vectors. Genomic DNA fragments can be amplified up to 15 kb. This kit does not contain 2.5 mM dNTPs.

The suggested working concentration range for the 10X GC Enhancer provided in this kit is 0.5-5X. A final concentration of 2 mM MgSO4 is sufficient to amplify most targets. Some targets may require a higher concentration of Mg2+ For optimal results, we recommend using a 100 mM MgSO4 stock solution to prepare a titration from 2 mM to 4 mM (final concentration) in 0.25 mM increments. 0.5 µl (2.5 U) of enzyme is sufficient for a reaction vlume of 50 µl. For increased amplification, up to 1 µl (5 U) of enzyme can be used.
