OR

biotechrabbit™ phi29 DNA Polymerase is an exceptionally pure DNA polymerase for demanding applications. The enzyme is purified from a recombinant E. coli strain carrying the phi29 DNA Polymerase gene from bacteriophage phi29.

The enzyme is a highly processive DNA polymerase (up to 70,000 base insertions per binding event) with a powerful strand-displacement activity and a 3'→ 5' proofreading exonuclease function.

phi29 DNA Polymerase proofreading activity acts preferentially on single-stranded DNA or RNA. Therefore, to avoid primer degradation during the DNA synthesis, 3' modified (protected) primers are highly recommended.

 

Component

Composition

phi29 DNA Polymerase

phi29 DNA Polymerase, 10 U/µl, in storage buffer containing 50% (v/v) glycerol.

10× phi29 Reaction Buffer

Optimized 10× phi29 reaction buffer.

 

STORAGE

-20°C (until expiry date – see product label)

 

Unit Definition

One unit is defined as the amount of polymerase required to convert 0.5 pmol of dTTP into acid insoluble material in 10 minutes at 30°C.

Quality Control
Protein Purity

Protein purity is analyzed by SDS polyacrylamide gel electrophoresis.

Exonuclease Activity

Linearized lambda/HindII fragments are incubated with the enzyme in a 50 µl reaction mixture for 4 h at 37°C. No degradation of DNA was observed.

Endonuclease Activity

lambda DNA is incubated with the enzyme in a 50 µl reaction mixture for 4 h at 37°C. No degradation of DNA was observed.

Nick Activity

Supercoiled plasmid DNA is incubated with the enzyme in a 50 µl reaction mixture for 4 h at 37°C. No conversion of covalently closed circular DNA to nicked DNA was detected.

Contamination with E. coli DNA

A sample of denatured enzyme is analyzed with specific primers targeting the 16S rRNA gene in qPCR for the presence of contaminating E. coli DNA. No E. coli DNA was detectable.
