    GenScript LApro Taq DNA Polymerase possesses both 3’->5’ proofreading activity and 5’->3’ DNA polymerase activity optimized to amplify longer GC-rich fragments.

    Description:
    GenScript LApro Taq DNA Polymerase possesses both 3->5 proofreading activity and 5->3 DNA polymerase activity optimized to amplify longer GC-rich fragments. As one of the most thermostable DNA polymerases known to have 3>5 proofreading activity, the enzyme catalyzes DNA synthesis at anoptimal temperature near 75℃ with very low error rate (it is about ten times more accurate than standard Taq DNA polymerase). The enzyme is optimized to achieve amplification of 17.5 kb products from human genomic DNA and 20 kb from λDNA. Using LApro Taq DNA Polymerase in long PCR* amplifications can reduce smearing and virtually eliminate unwanted background artifacts. LApro Taq DNA Polymerase can generate the A-ended PCR fragments required for T/A cloning.

    Key Features:

  • High capacity: One unit of enzyme can manage up to 20 kb from human genomic DNA.
  • High fidelity
  • Increased stability: LaPro Taq DNA Polymerase is more stable than standard Taq DNA polymerase.
  • Applications:
    Some of the applications of LApro Taq DNA Polymerase are as follows:

    • Up to 20kb from λDNA
    • High fidelity
    • More stable than normal Taq DNA Polymerase
    • TA cloning
    • Site-directed mutagenesis
    • Fragment analysis
