我们所展示的质粒图谱主要是从文献和开放数据库中收集而来,主要是为了方便研究工作,其中一小部分质粒进行了质量控制,可供科学家使用。

所有的产品都严格仅供科学研究使用,不能应用于临床试验,包括人体摄入、注射或外用的药理学用途。

确保质粒的关键元件正确,但是我们并不能保证实验结果。页面展示的图谱序列为理论序列,可能与测序结果不一致,请自行比对后确定是否满足要求。(如果测过序,本页面一般会提供下载)

开放数据库中的大多数载体序列都没有被完全测序。如果实际序列与参考序列的相似度超过99%,则将其视为正确。

由于科学研究是在探索未知,具有很大的不确定性,在任何情况下,我们都不承担超出质粒本身的额外经济损失或责任。

质粒操作方法

1. 发货形式:质粒干粉(常温运输,存于-20度,请务必先转化提质粒后使用)

2. 收到质粒干粉后请先5000rpm离心1min,再加入20μl ddH2O溶解质粒;(质粒复测的浓度有时候与标称值差距较大,这可能是因为冻干质粒在管中的位置、复溶效率、测量偏差以及管壁的吸附导致,因此建议先转化提质粒后再使用)

3. 取1支100μl 感受态于冰上解冻10min,加入2μl质粒,再冰浴30min后,42℃热激60s,不要搅动,再冰浴2min;

4. 加入900μl无抗的LB液体培养基,180rpm震荡37℃培养45min (30℃培养1-1.5小时);

5. 6000rpm离心5min,仅留100μl上清液重悬细菌沉淀,并涂布至目标质粒抗性的LB平板上;

6. 将平板倒置37℃培养14h,如果要求是30℃则培养20h; (菌落过多则将质粒稀释后再转化;没有菌落则加入10μl质粒转化;建议不要直接转表达感受态, 要先转克隆感受态,重提质粒后再导入表达感受态);

7. 挑取单菌落至LB液体培养基中,加入对应抗生素,220rpm震荡培养14h,根据实验需要和质粒提取试剂盒说明书提取质粒。
