General description

Benzonase® 核酸酶是一种用基因工程方法从粘质沙雷氏菌获得的核酸内切酶。它降解所有形式的DNA和RNA（单链、双链、线性和环状），而没有蛋白水解活性。它能够在较大范围的条件下工作，并且具有极高的比活度。该酶将核酸完全消化为长度为2至5个碱基（低于杂交极限）的5′-一磷酸酯化的寡核苷酸，非常适合从重组蛋白中去除核酸，从而符合FDA关于核酸污染的指南。Benzonase迅速水解核酸的能力使该酶成为降低粘度、减少加工时间并提高蛋白质产量的绝佳选择。例如，该酶与 BugBuster 和 PopCulture 蛋白质提取试剂兼容，因此可以与这些试剂一起添加，以消除大肠杆菌提取物中的粘度并去除核酸。

该酶包括两个 30kDa 的亚基。它在pH值6-10之间，温度0-42°C 起作用，并需要1-2mM Mg2+激活。该酶在离子和非离子型洗涤剂、还原剂、PMSF（1 mM）、EDTA（1 mM）和尿素（相对活性取决于特定条件）的存在下也具有活性。>150 mM单价阳离子，>100 mM磷酸盐，>100 mM硫酸铵或>100 mM盐酸胍能抑制其活性。

可提供超纯Benzonase 核酸酶（>99%，SDS-PAGE）和纯Benzonase核酸酶（>90%），标准浓度为25-29 U/µl，高浓度（HC）为250U/lµ。两种制剂均不含可检测的蛋白酶，并且比活度> 1 × 106蛋白。纯度>99%的产品经过内毒素测试，并含有<0.25 EU/1000 units. The product is suppliedas a 0.2 µm filtered solution in 50% glycerol.Store at -20°C.

Total endotoxin:<0.25 EU/1,000 units.Purity: >99%（SDS-PAGE）。

Other Notes

一个单位定义为在 30 分钟内导致ΔA₂₆₀为1.0的酶量，这对应于37 µg DNA的完全消化。

Acute treatment with replication-stalling chemotherapeutics causes reversal of replication forks. BRCA proteins protect reversed forks from nucleolytic degradation, and their loss leads to chemosensitivity.

TP53 deficiency is the most common alteration in cancer; however, this alone is typically insufficient to drive tumorigenesis. To identify genes promoting tumorigenesis in combination with TP53 deficiency, we perform genome-wide CRISPR-Cas9 knockout screens coupled with proliferation and transformation assays
