一般說明
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。

應用
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
特點和優勢
- 典型DNA得率：15 μg - 20 μg
- 提供有适用于革兰氏阳性菌和革兰氏阴性菌的实验方案
- 可在2小时内获得优质基因组DNA
- 可纯化出A260/A280 比率介于1.6-1.9之间的DNA
- 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
原則
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。
