HelixAmp™ DNA-free Taq polymerase is a recombinant enzyme expressed and purified from a bacterial host cell harboring Thermus aquaticus DNA polymerase gene and purified using a process that minimizes the level of contaminating host DNA. HelixAmp™ DNA-free Taq polymerase is a high-quality DNA polymerase and suited for molecular diagnostics. The contaminating host’s genomic DNA can cause  false-positive results, so the use of DNA-free Taq polymerase is very important in PCR detection of bacteria with universal primers(e.g. 16s rRNA specific primers). A chemically modified hot-start version of this enzyme, HelixAmp™ DNA-free Hot-Taq polymerase, is also available (see the product list).
