BstDNAPolymerase,ExonucleaseMinus,isarecombinantformofthe67kDaBacillusstearoThermophilusDNAPolymeraseprotein(largefragment).Theenzymehas5’-3’polymeraseactivityandstranddisplacementactivity,butitlacks3’-5’exonucleaseactivity.Italsohasreversetranscriptionactivity.
Lucigen'sBstDNAPolymerase,ExonucleaseMinus,hashigherstranddisplacementactivitythanthatofothersuppliers(Figure1).Theenzymecanbeusedinnucleicacidamplificationmethods*suchasisothermalamplification,wholegenomeamplification(WGA),andmultipledisplacementamplification(MDA).ItalsocanbeusedinNextGenerationsequencing.
Thisenzymehasoptimalactivityat65°C.ItissuitableforsequencingDNAwithhighGCcontentandsecondarystructures.Itisavailableinconcentrationsof8,000U/mlor50,000U/ml.
