质粒操作方法

质粒复溶方法

  1. 发货形式:质粒干粉,常温运输,收到后请于 -20 ℃ 保存,先转化提质粒再使用。
  2. 收到干粉后先 5000 rpm 离心 1 min,加入 20 μl ddH₂O 溶解。质粒复测浓度与标称值可能有差距,这通常来自干粉在管中的位置、复溶效率、测量偏差与管壁吸附,建议先转化提质粒后再使用。
  3. 取 1 支 100 μl 感受态细胞冰上解冻 10 min,加入 2 μl 质粒,冰浴 30 min,42 ℃ 热激 60 s(不要摇动),再冰浴 2 min。
  4. 加入 900 μl 无抗生素 LB 液体培养基,180 rpm、37 ℃ 振荡培养 45 min(30 ℃ 培养 1–1.5 h)。
  5. 6000 rpm 离心 5 min,保留约 100 μl 上清重悬菌体,涂布到对应抗性的 LB 平板。
  6. 平板倒置 37 ℃ 培养 14 h(30 ℃ 则 20 h)。菌落过多可稀释质粒后再转化;无菌落可增加至 10 μl 质粒。建议先转克隆感受态、重提质粒后再导入表达感受态。
  7. 挑取单菌落接种 LB 液体培养基,加入对应抗生素,220 rpm 振荡培养 14 h,按试剂盒说明提取质粒。

通用质粒转化方法

  1. 取100 μL感受态细胞置于冰上解冻10 min,加入2 μL质粒,冰浴30 min;随后42 ℃热激60 s,期间不要晃动,再冰浴2 min。
  2. 加入900 μL无抗LB液体培养基,37 ℃、180 rpm振荡培养45 min(30 ℃条件下则培养1–1.5 h)。
  3. 6000 rpm离心5 min,弃上清,仅保留100 μL上清重悬菌体沉淀,涂布于对应质粒抗性的LB平板上。
  4. 平板倒置培养,37 ℃培养14 h,或30 ℃培养20 h。
  5. 挑取单菌落至LB液体培养基中,加入对应抗生素,220 rpm振荡培养14 h;根据实验需求及质粒提取试剂盒说明书提取质粒。
