Summary. Plasmid purification is a technique used to isolate and purify plasmid DNA from genomic DNA, proteins, ribosomes, and the bacterial cell wall. A plasmid is a small, circular, double-stranded DNA that is used as a carrier of specific DNA molecules. When introduced into a host organism via transformation, a plasmid will be replicated

https://blog.addgene.org/plasmid-preps-different-purity-different-quantities-different-uses
Not all plasmid preps are the same. Before purifying a plasmid from a bacterial culture, it is important to consider your experiment. It will dictate the amount of DNA you need, and at which level of purity. Based on these premises we can classify a plasmid preparation in 3 different ways: Transformation grade DNA. Cloning grade DNA.

Plasmid purification is a common technique in most molecular biology labs. ... Plasmid copy number plays a significant role in determining the amount of plasmid DNA recovered from the prep. E. coli cultures were transformed with either a low copy or high copy number plasmid and grown for 18 hours in Lysogeny broth then an equal volume of

https://www.addgene.org/protocols/gel-purification/
Protocol: Gel Purification. Gel purification is most efficient with lower % agarose gels, so you will want to stay in the 0.7-0.8% range if possible. You will want nice crisp bands. This can be achieved by using a wider gel comb and running the gel at a lower voltage. You will want to have enough space around each band to cut without having DNA

Plasmid DNA (pDNA) is an important component of viral vector therapies. These circular double helix DNA molecules can be used as the therapeutic transgene, to code for the viral capsid or as the vaccine itself. DNA vaccines have been approved for use in animals and this approach is being leveraged to combat the SARS-CoV-2 virus.

https://blog.addgene.org/dna-purification-without-a-kit
This kit-free plasmid miniprep protocol from Addgene follows a similar workflow as a column-based plasmid extraction kit. First, you lyse the bacteria and denature the DNA and proteins in solution. The pH is then lowered using a renaturing solution, which causes the proteins and genomic DNA to precipitate. Plasmid DNA is free in solution.

Ostensibly, for pDNA manufacturing a high copy number is desired, and, indeed, an advantage of a high plasmid copy number is twofold: 1.) greater stability of the pDNA when random partitioning; and 2.) facilitating downstream purification as pDNA typically represents less than 3% of the macromolecules present in E. coli cell lysates (Bonturi N

Plasmid DNA (pDNA) production for mRNA, Plasmid-based DNA Vaccines, and Viral Vector Applications, involves a series of steps to grow, harvest, lyse, purify, and concentrate the DNA for further applications. Chromatography is used as part of the plasmid purification process, but the pDNA is often diluted during this step.

If you gel extract a fragment from a plasmid, you should probably expect the DNA concentration numbers (if using a spectrophotometer) to be low, because you will have started with a large plasmid (most likely around 5kb), then cut out a much smaller sub-fraction (perhaps 1kb), and the kits will never purify 100% back of the DNA from the gel.
