应用说明
Bst DNA聚合酶,核酸外切酶Minus,是67kDa嗜热脂肪芽孢杆菌 DNA聚合酶蛋白(大片段)的重组形式 。该酶具有5'-3'聚合酶活性和链置换活性,但缺乏3'-5'核酸外切酶活性。它还具有逆转录活性。
Lucigen的Bst DNA聚合酶,外切核酸酶Minus,具有比其他供应商更高的链置换活性(图1)。该酶可用于核酸扩增方法*,例如等温扩增,全基因组扩增(WGA)和多重置换扩增(MDA)。它也可用于下一代测序。
该酶在65°C时具有*活性。它适用于具有高GC含量和二级结构的DNA测序。它的浓度为8,000 U / ml或50,000 U / ml。
Bst DNA聚合酶,核酸外切酶Minus,提供有10X DNA聚合酶缓冲液B,其由200mM Tris-HCl pH 8.8,100mM(NH 4)2 SO 4,100mM KCl,20mM MgSO 4和1.0%Triton X-100组成。
Bst DNA Polymerase, Exonuclease Minus, is a recombinant form of the 67 kDa Bacillus stearothermophilus DNA Polymerase protein (large fragment). The enzyme has 5’-3’ polymerase activity and strand displacement activity, but it lacks 3’-5’ exonuclease activity. It also has reverse tran
Lucigen's Bst DNA Polymerase, Exonuclease Minus, has higher strand displacement activity than that of other suppliers (Figure 1). The enzyme can be used in nucleic acid amplification methods* such as isothermal amplification, whole genome amplification (WGA), and multiple displacement amplification (MDA). It also can be used in Next Generation sequencing.
This enzyme has optimal activity at 65°C. It is suitable for sequencing DNA with high GC content and secondary structures. It is available in concentrations of 8,000 U/ml or 50,000 U/ml.
Bst DNA Polymerase, Exonuclease Minus, is supplied with 10X DNA Polymerase Buffer B, composed of 200 mM Tris-HCl pH 8.8, 100 mM (NH4)2SO4, 100 mM KCl, 20 mM MgSO4, and 1.0 % Triton X-100.
图1. Lucigen Bst DNA聚合酶,核酸外切酶Minus,具有更大的链置换聚合酶活性。 将M13单链DNA与或不与8单位的Bst DNA聚合酶(+/- Bst)一起在制造商提供的反应缓冲液中,在有或没有复制引物(+/-引物)的情况下在65℃温育30分钟。MW,1 kb梯子。
Figure 1. Lucigen Bst DNA Polymerase, Exonuclease Minus, possesses greater strand-displacing polymerase activity. M13 single stranded DNA was incubated with or without 8 units of Bst DNA Polymerase(+/- Bst) in reaction buffer supplied by the manufacturer, with or without replication primer (+/- primer) for 30 minutes at 65°C. MW, 1 kb ladder.
