Description
Derived from our HiFi polymerase, the highQu ALLin™ Mega HS HiFi DNA Polymerase provides much lower error rate PCR with a 100 higher fidelity compared to Taq. Compared to Mega HiFi, this hot start enzyme version allows for even higher sensitivity and specificity of PCR as well as for a room-temperature reaction setup and is an excellent choice for multiplex reactions. The ALLin™ Mega HS HiFi DNA Polymerase is engineered to be much faster and to generate a higher yield of long PCR products up to 20 kb from complex GC-rich templates. Therefore the ALLin™ Mega HS HiFi DNA Polymerase is an excellent choice for long and very complex PCR applications where the highest fidelity is demanded. It is an enzyme of choice for cloning and all kind of sequencing applications including NGS. Generated blunt-ended PCR products are suitable for ligation into blunt vectors. To increase ligation efficiency, the use of HighEnd™ Repair Kit (HER0101) is recommended.
The convenience of ALLin™ Mega HS HiFi DNA Polymerase is maximized by the use of 2X Mastermix providing the additional advantage of reduced pipetting and minimized errors. The master mix is even supplied with PCR Water, and the only thing to add is the template with primers.
Protocols:
Important Notes
- Take typical measures to prevent PCR cross over contamination, keep your bench clean, wear gloves, use sterile tubes and filter pipet tips.
- Include a no-template control and positive control in parallel.
- Thaw and keep reagents on ice. Mix well before use.
- For complex, GC rich templates, use 99-100°C denaturation temperature, it might help to increase the yield.
- For established PCRs, try two-step cycling protocol with a combined annealing-denaturation step of 70°C (68°C to 75°C).
- Run an annealing temperature gradient (2°C increments) from 60°C to 66°C to choose the best conditions.
- The longer the amplicon, the longer the extension time: depending on the complexity of the template, perform extension from 10 sec/kb to 30 sec/kb. Longer extension for more complex templates is needed.
Prepare a 50 µl PCR reaction
| Rev. & For. Primers | variable, To 0.2 - 0.6 µM each (~2µl of 10 µM) |
| cDNA Template or gDNA Template |
<100 ng or 10 - 200 ng |
| PCR Water | to 25 μl |
| ALLin™ Mega HS HiFi Mastermix, 2X | 25 µl |
- Mix gently, avoid bubbles
- Place into the instrument set like:
| Initial denaturation | 1 cycle: 95°C - 1 min |
| Denaturation | 25-35 cycles: 95°C - 15 sec |
| Annealing | 25-35 cycles: 60-66°C- 15 sec |
| Extension |
25-35 cycles: 72°C – 30 sec (10-30 sec/kb) |
- After the PCR store probes shortly on ice, for long term store at -20°C.
