    Product Introduction

    Bst 2.0 DNA Polymerase displays improved amplification speed, yield and salt tolerance

    • Optimized for Loop-Mediated Isothermal DNA Amplification (LAMP)
    • Improved amplification reaction properties compared to Bst DNA Polymerase
    • Fast polymerization
    • Flexible reaction conditions including a higher salt tolerance and thermostability, as compared to wild-type Bst DNA Polymerase, Large Fragment (NEB #M0275)

    Product Information


    Bst 2.0 DNA Polymerase is an in silico designed homologue of Bacillus stearothermophilus DNA Polymerase I, Large Fragment (Bst DNA Polymerase, Large Fragment). Bst 2.0 DNA Polymerase contains 5´→3´ DNA polymerase activity and strong strand displacement activity but lacks 5´→3´ exonuclease activity. Bst 2.0 DNA Polymerase displays improved amplification speed, yield, salt tolerance and thermostability compared to wild-type Bst DNA Polymerase, Large Fragment.

    LAMP Salt Tolerance LAMP Salt Tolerance

    Performing LAMP reactions with increasing amounts of salt demonstrate increased resistance to inhibitors by using Bst 2.0. Bst 2.0 maintains high levels of activity where wild-type Bst DNA polymerase, large fragment, is completely inhibited.
    Rapid LAMP Detection Rapid LAMP Detection

    LAMP reactions amplifying different targets demonstrate a more rapid amplification threshold time using Bst 2.0 vs. Bst, large fragment.

    Product Source

    Bst 2.0 DNA Polymerase is prepared from an E. coli strain that expresses the Bst 2.0 DNA Polymerase protein from an inducible promoter.
