一般描述

GenElute 细菌基因组DNA试剂盒可以简单、方便地从革兰氏阴性菌中分离高纯度基因组DNA。对于大多数革兰氏阳性菌,本试剂盒必须结合选购的溶菌酶 (L4919)来有效裂解较厚的肽聚糖细胞壁。为方便您制备溶菌酶储液,我们提供了一种稀释的革兰氏阳性溶解溶液。

该试剂盒将硅胶膜系统的优势与微量离心形式结合在一起,同时无需采用昂贵的树脂、乙醇沉淀,以及诸如苯酚和氯仿等有害化学成分。

应用

纯化所得的细菌基因组DNA可用于以下游应用:
  • 限制性内切酶酶切
  • PCR
  • Southern印迹
  • 克隆

特点和优势

  • 起始材料:不超过1.5 mL培养物
  • 预期得率:至多20 μg
  • 洗脱体积:400 μl
  • 所需时间:70 - 120分钟
  • A260/A280比率:1.6 - 1.9
  • 无需苯酚、氯仿或乙醇沉淀步骤

原理

细菌首先在含有离液盐的溶液之中裂解,以确保大分子彻底变性。之后加入乙醇,从而使DNA在溶解物通过微量离心管在硅胶膜上离心时,结合到膜上。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得率取决于细菌培养物的细胞密度、细菌种属以及所用的菌株。通过GenElute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。
