质粒简介
  The vector pMAL-c5X is designed to produce maltose-binding protein (MBP) fusions, where the protein of interest can be cleaved from MBP with the specific protease Factor Xa . MBP fusions made with this vector are expressed cytoplasmically. The MBP has been engineered for tighter binding to amylose resin. A gene or open reading frame is inserted into a restriction site of the vector polylinker, in the same translational reading frame as the malE gene (encoding maltose-binding protein). The fusion protein thus produced can be purified by amylose affinity chromatography. The sequence coding for the four amino acids Ile-Glu-Gly-Arg is present just upstream of the XmnI site. This allows the protein of interest to be cleaved from maltose-binding protein with the specific protease Factor Xa. Fragments inserted in the XmnI site (cleaves GAAGG↓ATTTC) will produce a fusion protein that, after Factor Xa cleavage, contains no vector-derived residues on the protein of interest.

质粒菌株产品操作说明书
一、扩增流程
         收到产品后，请先根据产品管壁标签来判断产品形式，并在扩增前准确查找该质粒菌株的抗性、感受态和培养温度。
         1、质粒干粉（常温运输，存于-20度，90天保质期，请务必转化挑单克隆培养，不要直接使用和测序）
              ①收到质粒干粉后请先5000rpm离心1min，再加入20μl ddH2O去离子水溶解质粒；
              ②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；（从第二步开始均要在超净工作台中无菌操作）
              ③加入900μl无抗的LB液体培养基，180rpm震荡37℃培养45min；
              ④6000rpm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；（可使用本平台的平板涂布专用玻璃珠进行涂布，可以比传统涂布方法获得更多转化子）
              ⑤将平板正向培养1h，再倒置37℃培养14h。如果要求是30度则培养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。另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）
              ⑥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。
        2、甘油菌种（冰袋运输，存于-80℃，保质期90天，请务必划线挑单克隆培养）
              四区划线后挑单菌落培养，酵母菌需要先液体复苏再四区划线，再挑单菌落液体培养。
        3、穿刺菌种（冰袋运输，存于4℃，保质期7天）
              穿刺接种，液体培养后四区划线，再挑单菌落液体培养。
        4、菌落平板（冰袋运输，存于4℃，保质期7天）
              直接挑取单菌落至液体培养基中。
        5、液体质粒（冰袋运输，存于-20℃，保质期90天）
              单独提取的液体质粒收到后可直接使用。
        6、滤纸质粒（常温运输，存于-20度，90天保质期，请务必转化挑单克隆培养，不要直接使用和测序）
              收到货后将滤纸画圈部分剪下放入EP管中，加100ul无菌水将滤纸浸湿并浸泡5min，吸取5ul质粒转化，离心全涂。
