The efficacy of column-based plasmid purification doesn't just depend on how much plasmid is loaded onto the column, but also the total amount of biomass being loaded as well. (zymoresearch.com)
Yields of up to 10 mg (giga), 2.5 mg (mega), 500 µg (maxi), and 100 µg (midi) transfection-grade, high-copy plasmid DNA are achieved from culture (culture volumes depend on plasmid copy number, size of insert, host strain, and culture medium). (qiagen.com)

We have completed the methodological development and verification of more than ten GMP plasmid products. (ubrigene.com)

For purification of up to 50 micro g high-quality plasmid DNA in 96-well format. (labsave.com)
We leverage comprehensive quality systems to deliver high-quality plasmid consistently and predictably. (trilinkbiotech.com)

The use of silica membrane-based DNA purification kits is a convenient way to prepare plasmid DNA samples for cloning or subsequent analysis, e.g. sequencing or restriction analysis. (integra-biosciences.com)
The purified plasmid can be used directly for automated fluorescent sequencing. (toyobo-global.com)

The HiScribe SP6 RNA Synthesis Kit from NEB is faster and achieves higher yields for RNAs of various lengths. (neb.com)
CIM ® monoliths are available in a variety of chemistries and sizes ranging from screening to commercial processing for higher yields and improved speed. (sartorius.com)

With flow-independent performance, low back-pressure, and versatility our monolithic columns facilitate faster purification of your viruses or nucleic acids. (sartorius.com)

Then, the purified plasmid DNA was digested by restriction enzymes. (toyobo-global.com)
Digesting the human genome with restriction enzymes would yield about two million DNA fragments, which is far too many to separate from each other for the purposes of isolating one specific DNA sequence. (addgene.org)

Endotoxins (also known as lipopolysaccharides or LPS) are often co-purified with plasmid DNA and significantly reduce transfection efficiencies in endotoxin-sensitive cell lines. (sigmaaldrich.com)

Biomass, yield, and plasmid quality are assessed to maximize productivity and quality for downstream applications. (vgxii.com)
