Product information "Hotstart G5 HiFi DNA Polymerase"

G5 HiFi DNA Polymerase is a thermostable enzyme with 5'-3 'DNA polymerase and 3'-5' proof-reading exonuclease activity with additional hotstart technology (inactive before first heating above 60°C). The enzyme shows an extremely high amplification accuracy at a very high speed with a very low error rate (about 200 times more accurate than Taq polymerase).

The G5 HiFi DNA Polymerase comes with two different 5-fold buffers. Buffer A is intended for the stable and reproducible amplification of long fragments. Buffer B is optimized for the amplification of GC-rich or complex templates. Both buffers already contain dNTPs. The optimized G5 HiFi polymerase buffers offer very high accuracy (200 times higher than Taq DNA polymerase), high performance and better success in amplifying of complex or longer templates, unpurified sample material at fast cycle times.

Features:
- High Fidelity proofreading DNA polymearse.
- Extrem high amplification rate (>6000bp per minute).
- Error rate about 6-times less than that of Pfu or Pwo, about 50-times less compared to Taq.
- For long PCR fragments (up to 20 kb for plasmid DNA or up to 7 kb for genomic DNA.
- 5'-3' polymerase acitivity and 3'-5' exonuclease activity.
- generates blund ends.
- ExactRun DNA Polymerase is supplied with buffer and separate MgCl2.

Reaction conditions may differ from PCR protocols already in use, as ExactRun DNA Polymerase tends to need higher denaturation and annealing temperatures. Especially annealing temperature may differ significantly from that of Taq DNA polymerase.


- The amount of enzyme depends on the amount of template and the length of the amplicon. Usually 1 unit ExactRun per 50µL reaction volume is enough for good results, but the optimal amount can range from 0.25 to 2 units per 50µL reaction.
It is highly recommended not to exceed 2 units/50µL!

- When cloning fragments amplified with ExactRun DNA Polymerase, blunt end cloning is possible. If TA cloning is required please refer to page 5 (Using PCR-product for T/A-cloning).

- The concentration of Mg2+ is critical for PCR. Excessive Mg2+ stabilises the DNA double strand. Excess Mg2+ can also stabilize spurious annealing of primers to incorrect template sites and decrease specificity. Inadequate Mg2+ may lead to lower product yield. The optimal Mg2+ concentration depends on the dNTP concentration, the specific template DNA and the sample buffer. In general, the optimal Mg2+ concentration is ca. 1mM over the total dNTP concentration for standard PCR. If any component of the PCR reaction contains EDTA or EGTA, the apparent Mg2+ optimum may be shifted to higher concentrations.

- PCR additives / DMSO: Some publications recommend to add 3% DMSO for GC-rich templates, which shall aid to denature DNA. In some cases DMSO may also be required for supercoiled plasmids. Other additives as formamide, glycerol, and betaine can also be used together with ExactRun.
At high concentrations of DMSO the annealing temperature has to be reduced between 3°C and 6°C.

- Primer annealing: For primers >20nt use an annealing temperature of 5°C above the lower primer Tm.
For primers <20nt use an annealing temperature of 7°C above the lower primer Tm.
Anneal for 10 – 30 sec.
A 2-step PCR protocol is recommended when primer Tm values are at least 69°C.
Extension depends on template length and complexity We recommend an extension rate of 15 sec./kb for low complex DNA (plasmids, lambda DNA or BAC-DNA) and an extension rate of 30 sec/kb for high complex DNA (genomic). Sometimes extension rates have to be decreased down to 40 sec/kb.
