质体DNA的纯化(Purification of plasmid DNA) 登录以编辑 原理[] 少量制备质体DNA,在基因选殖(gene cloning) 是一个不可或缺的步骤,利用快速制备质体DNA,经过鉴识酵素(restriction enzyme)消化作用,电泳分析后,可以很快的筛选出许多转形的品系(clone)。以便找出有兴趣或是预期的品系,再利用大量制备法,把DNA大量制备...
p>A simple, scalable method for purification of plasmid DNA is described. The method includes modification of the classical alkaline-lysis-based plasmid extraction method by extending the solubilization step from less than 30 min to 24 h. The extraction is followed by the novel use of tangential...
We were able to reduce both the time and the use of hazardous chemicals associated with the previous plasmid isolation methods of high-pressure liquid chromatography and CsCl gradient centrifugation by employing fast protein liquid chromatography (FPLC). Plasmid was first crudely prepared from bacterial...

The aim of this study is to prepare megaporous dye-affinity cryogel discs for the purification of plasmid DNA (pDNA) from bacterial lysate . Poly(hydroxyethyl methacrylate) [PHEMA] cryogel discs were produced by free radical polymerization initiated by N,N,N′,N′-tetramethylene diamine (TEMED)...
plasmidpre-purificationtangential flow filtrationThe growing demand of plasmid DNA for gene therapy and third generation vaccines has encouraged the development of simple, robust and scalable production bioprocesses. Bearing in mind the purification step, the membrane separation processes may be a viable ...
Large-Scale, Nonchromatographic Purification of Plasmid DNA A large-scale approach to the purification of plasmid DNA has been developed that overcomes many of the limitations of current chromatography-based process... JC Murphy,MA Winters,SL Sagar - Humana Press 被引量: 9发表: 2006年 Selective ...
After IMAC chromatography, high purity supercoiled DNA is recovered in good yields of 100-150 g plasmid per 200 mL shake flask culture. Moreover, the resulting DNA is free from linear or open-circular plasmid DNA, genomic DNA, RNA, and protein, to the limits of our detection. Furthermore,...
PURIFICATION OF SUPERCOILED PLASMID DNAThis invention comprises a process of purifying supercoiled plasmid DNA of purity and characteristics required for use in a DNA vaccine or in Gene Therapy or in uses where high purity supercoiled plasmid DNA is required, from a genetically transformed bacterium ...
