Description

φ29 DNA Polymerase is a highly processive polymerase from
Bacillus Subtilis
phage φ29. It has exceptional strand displacement and processive synthesis properties, which allows for highly efficient isothermal DNA amplification. The enzyme possesses a 3'→5' exonuclease (proofre
ADI
ng) activity acting preferentially on single-stranded DNA, allowing high-fidelity DNA synthesis.



Applications



Rolling circle amplification (RCA): generation of periodic DNA nanotemplates

Multiple displacement amplification (MDA)

Unbiased amplification of whole genome (WGA):

amplification of DNA for SNP and STR detection

cell-free amplification of DNA from single cells

pathogenic organisms or metagenomes

amplification of DNA from filter paper blood spot samples



DNA template preparation for sequencing

Protein-primed DNA amplification

In situ
genotyping with padlock probes

Recombination based-cloning

Cell-free cloning of lethal DNA

RNA-primed DNA amplification





Source

A recombinant
E. coli
strain carrying the phi29 DNA Polymerase gene from bacteriophage phi29
