Bst 2.0 DNA Polymerase(iGlycerol free)
I-Bst DNA polymerase V2 ivela kwi-Bacillus stearothermophilus DNA Polymerase I, enomsebenzi we-5′→3′ DNA polymerase kunye nomsebenzi oqinileyo wokutshintshwa kwekhonkco, kodwa akukho 5′→3′ umsebenzi we-exonuclease.I-Bst DNA Polymerase V2 ifanelekile ngokufanelekileyo kwi-strand-displacement, isothermal amplification LAMP (i-Loop mediated isothermal amplification) kunye nokulandelelana ngokukhawuleza.

Usetyenziso
1.LAMP isothermal amplification
2.DNA strand single displacement reaction
3.High GC gene ulandelelwano
4.Ukulandelelana kweDNA kwinqanaba le-nanogram.
Imeko yoGcino
Ukuthutha ngaphantsi kwe-0°C kwaye igcinwe kwi-25°C~-15°C.
Inkcazelo yeyunithi
Iyunithi enye ichazwa njengobungakanani be-enzyme edibanisa i-25 nmol ye-dNTP kwizinto ezingenayo i-asidi kwimizuzu engama-30 kwi-65 ° C.
Ulawulo lwemeko
1.Uvavanyo lweProtein Purity Assay (SDS-PAGE):Ukucoceka kwe-Bst DNA polymerase V2 ≥99% igqitywe luhlalutyo lwe-SDS-PAGE usebenzisa i-Coomassie Blue ubhaqo.
2.Umsebenzi we-Exonuclease:Ukufukanyelwa kwe-50 μL reaction equlathe ubuncinci be-8 U ye-Bst DNA polymerase V2 ene-1 μg λ -Hind Ⅲ yokwetyisa i-DNA iiyure ezili-16 ngama-37 ℃ kubangela ukuba kungabikho kuthotywa kubonwa njengoko kumisiwe.
3.Umsebenzi we-Nickase:Ukufukanyelwa kwe-50 μL reaction equlathe ubuncinci be-8 U ye-Bst DNA polymerase V2 ene-1 μg pBR322 DNA iiyure ezili-16 kuma-37°C ibangela ukuba kungabikho kuthotywa kubonwa njengoko kumisiwe.
4.Umsebenzi we-RNase:Ukufukanyelwa kwe-50 μL reaction equlathe ubuncinci be-8 U ye-Bst DNA polymerase V2 ene-1.6 μg MS2 RNA ngeeyure ezili-16 kuma-37°C ibangela ukuba kungabikho kuthotywa kubonwa njengoko kumisiwe.
5.E. coli DNA:I-120 U ye-Bst DNA polymerase V2 ihlolwe ubukho be-E. coli genomic DNA kusetyenziswa i-TaqMan qPCR kunye ne-primers ekhethekileyo ye-E. coli 16S rRNA locus.Ungcoliseko lwe-E. coli genomic DNA yi ≤1 Ikopi.
