Thermo Scientific EquiPhi29 DNA Polymerase is a proprietary phi29 DNA polymerase mutant developed through in vitro protein evolution. This enzyme is significantly improved over phi29 DNA polymerase in protein thermostability, reaction speed, product yield, and amplification bias, while retaining all the benefits of the wild-type enzyme.

EquiPhi29 DNA Polymerase possesses strong strand displacement activity and 3'→5' proofreading exonuclease activity that acts preferentially on single-stranded DNA or RNA.

Features of EquiPhi29 DNA Polymerase
• Highest processivity and strand displacement activity—more than 70 kb long DNA stretches can be synthesized
• Low amplification bias
• Extremely high yields of amplified DNA, even from small amounts of template
• Highly accurate DNA synthesis in a short time 

Applications
EquiPhi29 DNA Polymerase may be used in a wide variety of applications including:
• Unbiased whole genome amplification (WGA)
• Rolling circle amplification (RCA)
• Protein-primed DNA amplification
• Cell-free cloning of lethal DNA
In situ genotyping with padlock probes
• RNA-primed DNA amplification

Notes
1. The addition of pyrophosphatase to the reaction mixture with EquiPhi29 DNA Polymerase may further enhance DNA synthesis
2. Because of the enzyme's 3'→5' proofreading exonuclease, 3’-modified primers are highly recommended.
3. EquiPhi29 DNA Polymerase can amplify DNA in a wide range of temperatures (30–45°C), with an optimal reaction temperature of 42°C.

Can I use EquiPhi29 DNA Polymerase to incorporate 5-methyl-dCTP?

Thermo Scientific EquiPhi29 DNA Polymerase is a proprietary mutant phi29 DNA Polymerase developed through in vitro protein evolution. EquiPhi29 DNA Polymerase as well as phi29 DNA Polymerase should be able to incorporate 5-methyl-dCTP nucleotides and other modified nucleotides.

When using EquiPhi29 DNA Polymerase, do I need to purify amplified DNA products before downstream applications?

Cleaning of the amplified product is not required prior to several downstream methods (e.g., debranching, digestion with restriction endonucleases, Sanger sequencing); the dilution of amplified product is sufficient. If the clean-up procedure is needed, we recommend using an affinity-based spin-column or magnetic bead-based purification method.

What is the minimal recommended time for amplification with EquiPhi29 DNA Polymerase?

The optimal reaction time for DNA amplification with EquiPhi29 DNA Polymerase is 2 hours. For samples with ≥1 pg of DNA input, DNA amplification time can be shortened to 1 hour if maximizing product yield is not essential.

Can liquid media culture or colonies be used as a starting material for amplification with EquiPhi29 DNA Polymerase?

Yes. EquiPhi29 DNA Polymerase can work with different types of sample input material such as purified DNA, liquid media culture, agar plate colonies, etc.
