WebJul 11, 2012 · Large molecular weight plasmids are often used in gene therapy and DNA vaccines. To investigate the effect of plasmid size on the performance of Escherichia coli host strains during plasmid preparation, we employed E. coli JM109 and TOP10 cells to prepare four plasmids ranging from 4.7 to 16.8 kb in size. Each plasmid was extracted … WebIn transformation, a bacterium takes in DNA from its environment, often DNA that's been shed by other bacteria. In a laboratory, the DNA may be introduced by scientists (see biotechnology article). If the DNA is in the form of a circular DNA called a plasmid, it can be copied in the receiving cell and passed on to its descendants.

WebAbstract. Lipid nanoparticles (LNPs) containing distearoylphosphatidlycholine (DSPC), and ionizable amino-lipids such as dilinoleylmethyl-4-dimethylaminobutyrate (DLin-MC3-DMA) are potent siRNA delivery vehicles in vivo. Here we explore the utility of similar LNP systems as transfection reagents for plasmid DNA (pDNA). WebThe plasmid DNA might be used in further DNA cloning steps (e.g., to build more complex plasmids) or in various types of experiments. In some cases, plasmids are directly used … stray plants
