BioReady Pfu

DNA Polymerase

Highest Fidelity PCR

Evolution delivers PCR with fewer errors

Pfu DNA polymerase is a thermostable DNA polymerase isolated from Pyrococcus furiosus. This well-characterized enzyme was the first to be shown to exhibit 3’ → 5’ exonuclease activity – necessary for proof reading. The result are PCR products with much lower error rates as compared with taq-based polymerases. The improved fidelity makes BioReady Pfu a great choice for certain applications including: template production for DNA sequencing, cloning and site-directed mutagenesis..


It ain’t rocket science any more

PCR used to be considered an art. But over the past 30 years since its general acceptance into scientific experimentation, PCR has become one of the best characterized bio-enzymatic processes. To this end, we ask you this simple question: Why pay prices that do not reflect this fact? All of Bulldog Bio’s PCR products are priced fairly and promise satisfying results. It’s that simple..
