Plasmid DNA Production

Plasmid DNA is used for a number of downstream applications such as transfection, sequencing, screening clones, restriction digestion, cloning, and PCR. A number of methods have been developed for the purification of plasmid DNA from bacteria. The most common method that is used is based on the alkaline lysis method. Nowadays, a variety of convenient and fast plasmid DNA purification kits are commercially available ensuring advanced quality and purity. The size of the bacterial culture used (and effectively the plasmid DNA yield) defines the plasmid preparation as miniprep, midiprep, maxiprep etc. The small-scale mini preparation of plasmid DNA is commonly used to screen bacterial clones for the presence of recombinant DNA inserts.

Overall solutions

  • CD BioSciences uses self-developed cloning technology, combined with a uniquely designed vector system, we have established a variety of stock plasmid libraries, including human ORF cDNA cloning library, human microRNA cloning library, human shRNA cloning library, and human gRNA pool cloning Library and mouse gRNA pool clone library.
  • CD BioSciences spot plasmid library products have a large variety and short delivery time, which can meet the different experimental needs of scientific researchers.
  • Endotoxin-free DNA is essential for sensitive cell culture and in vivo experiments. CD BioSciences can produce almost endotoxin-free plasmid DNA in a variety of scales (maximum 1 gram). The endotoxin levels in all delivered endotoxin-free samples were on average less than 100 EU per mg of DNA. The final product is verified by restriction digestion or sequence analysis, and other analyses can be provided upon request.
