一般說明
GenElute HP 无内毒素质粒大量制备试剂盒可以简单、快速地从重组大肠杆菌培养物中分离不含内毒素的质粒DNA。该试剂盒采用了可快速澄清细菌裂解液的滤柱和可捕获质粒DNA的硅胶柱。配套的专利溶液可使质粒DNA结合到结合柱上,同时避免内毒素随之吸附。该技术使得用户可以维持一致的、低于 0.1 EU/μg 质粒DNA的内毒素水平。
制备所得的优质、不含内毒素DNA可直接供包括内毒素敏感细胞转染等最严格的应用使用。
制备所得的优质、不含内毒素DNA可直接供包括内毒素敏感细胞转染等最严格的应用使用。
Sigma Life Science致力于为您提供符合一项或多项绿色化学十二条原则 (The 12 Principles of Greener Chemistry),更环保的替代产品。相对于使用苯酚和氯仿进行DNA提取的标准方法,本产品符合固有安全化学原则(Inherently Safer Chemistry)。
特點和優勢
- 可纯化出多达1.2 mg内毒素水平≤0.1 EU/μg高拷贝数质粒DNA
- 从沉淀细胞到获得纯化的质粒,仅需35分钟
- 方便的真空形式
原則
通过离心分离法收集过夜的重组大肠杆菌培养液,然后通过改性SDS 碱裂解法进行处理。过滤澄清裂解液,然后加入针对无内毒素质粒制备而优化的结合溶液。随后,质粒捕获到硅胶膜上,同时避免内毒素随之吸附到膜上。通过两遍洗涤步骤,去除污染物。最后,在不含内毒素的水中洗脱结合所得的DNA。回收的质粒DNA主要以超螺旋形式存在。所含的基因组DNA和RNA均低于溴化丙啶染色琼脂糖凝胶电泳的检测水平。
