质粒简介
Backbone pComb3X containing PCR template for human antibody lambda light chain constant region.
pComb3X is the newest of the pComb vectors. Improvements over pComb3 include increased stability and introduction of an asymmetric SfiI cassette for directional cloning of full Fab, scFv, peptide and other protein for phage display. 6xHis and HA tags allow for purification and detection. An amber stop codon was introduced to turn-off expression of the pIII fusion protein by switching to a non-supressor strain of E. coli allowing production of soluble protein without subcloning. Alternatively, the gene for phage protein pIII can be removed by SpeI/NheI digest. pComb3XLambda can be used as a template to amplify the lambda light chain constant region for construction of chimeric antibody libraries as described in:
Barbas, C. F., III; Burton, D. R.; Scott, J.K., Silverman, G.J. Eds. (2001) Phage Display: A Laboratory Manual; Cold Spring Harbor Laboratory Press: Cold Spring Harbor, New York
Please note that there is a A246V mutation in heavy chain region; however, this vector is meant to be used as a PCR template for the light chain region from base# 613-1016.
质粒图谱
pComb3XLambda噬菌体展示质粒使用说明:
1、收到质粒干粉后请先5000rpm离心1min,再加入20μl无菌水溶解质粒,室温放置1min;
2、从-80℃冰箱中取出相应的感受态,置于冰盒上解冻,并做好标记;
3、取2μl质粒加至100μl感受态中,冰浴30min;
4、42℃热激90s,再冰浴2min;
5、加入900μl无抗的LB液体培养基,180rpm震荡培养45min;
6、6000rpm离心5min,仅留100ul上清混匀菌体沉淀;
7、混匀后的菌液加至对应抗性的LB平板上,倒入适量玻璃珠,涂匀液体;
8、将平板正向培养1h,再倒置培养12h~16h;
9、挑取单克隆菌落至对应抗性的LB液体培养基中,震荡培养12h~16h,根据实验需要提取质粒。
pComb3XLambda噬菌体展示质粒注意事项:
1、如果您收到的是甘油菌种,请先四区划线,挑取单克隆培养。
2、如果第二天转化平板长的过多,请将质粒按比例稀释后再转化。
