The isolation of DNA from bacteria, described in this protocol, relies upon the use of sodium dodecyl sulfate and proteinase K to lyse the cells. High-molecular-weight DNA is then sheared (to reduce its viscosity and make it more manageable), extracted with phenol:chloroform, and precipitated with isopropanol. DNA isolated according to this procedure ranges from 30 to 80 kb in length.
本实验方案中所描述的从细菌中分离DNA的方法，依赖于使用十二烷基硫酸钠和蛋白酶K来裂解细胞。然后将高分子量的DNA进行剪切（以降低其粘度并使其更易于处理），用酚：氯仿进行提取，并用异丙醇沉淀。按照此程序分离得到的DNA长度在30至80 kb之间。
