一般描述

GenElute哺乳动物基因组DNA纯化试剂盒可以简单、方便地从多种哺乳动物源样本中分离高纯度的大分子量DNA。此类试剂盒使用了为基因组DNA纯化精选的硅胶膜,采用了方便的离心柱形式。

起始材料首先使用含有离液盐的溶液进行裂解,以确保大分子彻底变性。之后加入乙醇,当裂解物离心通过微量离心管时DNA会结合在硅胶膜上。在洗涤去除污染物后,将DNA放在200 μL的Tris-EDTA溶液中洗脱。预期的基因组DNA得率很大程度上取决于所用的起始材料用量及类型。通过本试剂盒纯化所得的DNA的A260/A280比率介于1.6-1.9之间,最大长度可达50 kb。

纯化所得的基因组DNA可直接用于限制性酶切、PCR、Southern印迹、测序反应等下游应用。

应用

纯化所得的基因组DNA可直接供以下下游应用使用:
  • 限制性内切酶酶切
  • PCR
  • Southern印迹
  • 测序反应
  • 克隆
  • 连接

特点和优势

  • 预期得率:25 μg / 2 x 106个培养细胞;30 μg / 25 mg组织
  • 洗脱体积:200 - 400 μl
  • 所需时间:细胞裂解后20分钟
  • A260/A280比率:1.6 - 1.9
  • 是否需要机械式均质化:否

原理

起始材料首先使用含有离液盐的溶液进行裂解,以确保大分子彻底变性。之后加入乙醇,裂解物离心通过微量离心管时,DNA会结合到硅胶模上。在洗涤去除污染物后,将DNA放在200 μL的Tris-EDTA溶液中洗脱。预期的基因组DNA得率很大程度上取决于所用的起始材料用量及类型。通过本试剂盒纯化所得的DNA的A260/A280比率介于1.6-1.9之间,最大长度可达50 kb。
