Description

Product Information

Genie Fusion Ultra High-Fidelity Red 2x Master Mix contains a next generation enzyme with a loading dye for robust PCR with ultra high-fidelity. With extremely low error rates x53-fold lower than Taq, Genie Fusion Ultra High-Fidelity DNA Polymerase sets a new level of performance for standard and long fragment PCR amplification.

Employing a unique extension factor as well as specificity-promoting and plateau-inhibiting factors, Genie Fusion greatly improves long range PCR amplification, specificity, and PCR yield. Genie Fusion is capable of amplifying long fragments such as 40 kb λ DNA, 40 kb plasmid DNA, 20 kb genomic DNA and 10 kb cDNA. In addition, Genie Fusion has excellent resistance to PCR inhibitors and can be used for direct PCR amplifications of bacteria, fungi, plant tissues, animal tissues, and even whole blood samples. Genie Fusion contains two monoclonal antibodies inhibiting the 5´→3´ polymerase activity and 3´→5´ exonuclease activity at room temperature which enables Genie Fusion to perform super-specific Hot-Start PCR.

Genie Fusion Ultra High-Fidelity Red 2X Master Mix contains Genie Fusion Ultra High-Fidelity DNA Polymerase, dNTPs and an optimized buffer system containing a loading dye. Protective agents in the Genie Fusion Ultra High-Fidelity Red 2X Master Mix allow for repeat freeze-thaw cycles while maintaining excellent performance. Amplification generates blunt-end products which are compatible with GenieClone DNA Assembly Cloning Kit (Assay Genie, Cat. No. #MORV0004).

a. For pre-denaturation, the recommended temperature is 95℃, and the recommended time is 30 sec for plasmid / virus DNA and 3 min for genomic DNA / cDNA.

b. For annealing, the recommended temperature is the Tm of the primers. If the Tm of the primers is higher than 72℃, the annealing step can be removed (two-step PCR). If necessary, annealing temperature can be further optimized in a gradient. In addition, the amplification specificity depends directly on the annealing temperature. Raising annealing temperature is helpful to improve poor amplification specificity.

c. Longer extension time is helpful to increase the amplification yield.

6.2 For Long-fragment PCR

Genie Fusion Ultra High-Fidelity DNA Polymerase can perform a long-range amplification with high specificity and yields. If the standard PCR protocol (Section 6.1) yields insufficient results, the following Touch-Down, two-step PCR is recommended.

7. Application Examples

Note: See technical manual for application examples.

8. Notes

  1. Use high-quality templates.
  2. Do not use dUTP or any primers or templates that contain uracil.
  3. The Genie Fusion Ultra High-Fidelity Polymerase has strong proofreading activity. Therefore, the PCR products must be purified before adding A-Tailing when TA cloning.
  4. Primers design notes:
  • Choose C or G as the last base of the 3’-end of the primer.
  • Avoid continuous mismatching at the last 8 bases of the 3’-end of the primer.
  • Avoid hairpin structures at the 3’-end of the primer.
  • Tm of the primers should be within the range of 55℃ - 65℃ (recommend to calculate in Primer Premier 5), and the Tm difference between F and R primers should be less than 1℃.
  • Additional sequence should not be included when calculating Tm of the primers.
  • GC content of the primers should be within the range of 40% - 60%.
  • The general distribution of A, G, T, C in the primers should be uniform, and avoid using regions with rich GC and rich AT.
  • Keep complementary sequence less than 5 bases within the primers or between two primers, and complementary sequence less than 3 bases at the 3’-end of the primers.
  • Please search the specificity of the designed primers by NCBI BLAST to avoid non-specific amplification.
