Bst 2.0 DNA Polymerase (Glycerol dawb)
Bst DNA polymerase V2 yog muab los ntawm Bacillus stearothermophilus DNA Polymerase I, uas muaj 5′ → 3′ DNA polymerase kev ua thiab muaj zog saw hloov ua haujlwm, tab sis tsis muaj 5′→ 3′ exonuclease kev ua.Bst DNA Polymerase V2 yog qhov tsim nyog rau strand-hloov chaw, isothermal amplification LAMP (Loop mediated isothermal amplification) thiab ceev sequencing.
