Extraction of plasmid DNA by alkaline lysis(碱裂解法抽提质 粒DNA) Experiment 1. Extraction of plasmid DNA by alkaline lysis [experimental principle] Plasmids are small, double stranded, ring-shaped DNA found in vitro, ranging in size from 1-200kb to autonomously replicating in host bacteria. In...
and the DNA fragment being joined to the vector fragment and not having anorigin of replicationis called an insert. This classification is somewhat artificial; indeed, different vector fragments can be joined together to produce bi-replicon plasmids. Insertion into acloning vectorand...
recombinant dna plasmid, bacteria containing it and method for the manufacture of a genprodukt of plasmid dnaGUSTAFSSON, PETTERMOLIN, SOERENUHLIN, BERNT ERICNORDSTROEM, KURT
This chapter explains the plasmid mini-prep method, which is useful for preparing partially purified plasmid DNA in small quantities from a number of transformants. It relies on an alkaline SDS lysis to free the plasmid DNA from the cell, leaving behind the E. coli chromosomal DNA with a cel...

A rapid microscale technique for isolation of recombinant plasmid DNA suitable for restriction enzyme analysis A simple and rapid microscale technique is described for the isolation of plasmid DNA which involves cell lysis with phenol, centrifugation, phenol extraction, ethanol precipitation, and RNase dig...
The hepatocytes located in bottom after centrifuge at 200g for 10min were collected for genomic DNA extraction. Lung transvascular albumin flux assessment The EBA flux assay was carried out as described previously (Huang et al., 2016). Briefly, Evans blue dye (Sigma Aldrich) was dissolved in ...
NucleoBond PC 100 plasmid midiprep kits allow you to purify plasmid DNA in just a few hours without phenol/chloroform extraction. These kits can be used to purify high- and low-copy-number plasmids, cosmids, BACs, PACs, and YACs grown from bacterial cultures. The resulting plasmids are at...
For pharmaceutical applications of plasmid DNA, either direct or indirect, certain quality standards are required. Whereas for direct gene transfer into human “Good Manufacturing Practice” (GMP) grade is mandatory, for GMP production of, e.g., viral...
plasmid DNA into the three different forms, supercoiled (form I), nicked circle (form II), and linearized (form III), and the desired plasrnid form is collected. Further extraction with butanol is required to remove residual ethidium bromide followed by DNA precipitation using alcohol. Additional...
