Preparation of Plasmid DNA

Current Protocols in Protein Science, 1998
AbstractThis appendix presents basic procedures for alkaline lysis minipreps, both in tubes and in microtiter plates, and also provides an for boiling lysis. A describes storage of plasmid DNA.

Pharmacokinetics of Plasmid DNA in the Rat

Pharmaceutical Research, 2001
The pharmacokinetics of plasmid DNA after IV bolus administration in the rat by following supercoiled (SC), open circular (OC), and linear (L) pDNA forms of the plasmid.SC, OC, and L pDNA were injected at 2,500, 500, 333, and 250 microg doses.

Affinity Adsorption of Plasmid DNA

Biotechnology Progress, 2004
The development of a protein-mediated dual functional affinity adsorption of plasmid DNA is described in this work. The affinity ligand for the plasmid DNA comprises a fusion protein with glutathione-S-transferase (GST) as the fusion partner with a zinc finger protein.

Production of Plasmid DNA as Pharmaceutical

2015
Pharmaceutical applications of plasmid DNA require certain quality standards, depending on the intended use of the plasmids. That is, for direct gene transfer into human, GMP Grade is mandatory, however, for GMP production of for example viral vectors (AAV or mRNA etc.), the plasmid DNA used has not to be produced under GMP necessarily.

The Ribosomal DNA Plasmids of Entamoeba

Parasitology Today, 1998
In most organisms, the nuclear ribosomal RNA (rRNA) genes are highly repetitive and arranged as tandem repeats on one or more chromosomes. In Entamoeba, however, these genes are located almost exclusively on extrachromosomal circular DNA molecules with no clear evidence so far of a chromosomal copy.

Radioprotection of plasmid DNA by oligolysines

International Journal of Radiation Biology, 2004
To define ionic conditions under which oligolysines condense DNA as assayed by radioprotection of a plasmid substrate. And to compare these conditions with those required by the well-characterized ligands spermidine and hexammine cobalt (III). This will enable a reversible compaction model for plasmid DNA to be devised that models more closely ...

Phytoplasma Plasmid DNA Extraction

2012
Phytoplasma plasmids have generally been detected from DNA extracted from plants and insects using methods designed for the purification of total phytoplasma DNA. Methods include extraction from tissues that are high in phytoplasma titre, such as the phloem of plants, with the use of CsCl-bisbenzimide gradients that exploit the low G+C content of ...

Triplex DNA in plasmids and chromosomes

Gene, 1989
Circular plasmids containing pyrimidine purine tracts can form both inter-and intramolecular triplexes. Addition of poly(dTC) to plasmid pTC45, which contains a (TC)45.(GA)45 insert, results in intermolecular triplex formation. Agarose-gel electrophoresis gives rise to many well-resolved bands, which correspond to 1, 2, 3, 4...

Rapid screening for plasmid DNA

Molecular and General Genetics MGG, 1977
A procedure is described for demonstrating plasmid DNA and its molecular weight, based on rate zonal centrifugation of unlabelled DNA in neutral sucrose gradients containing a low concentration of ethidium bromide. Each DNA species is then visualized as a discrete fluorescent band when the centrifuge tube is illuminated with ultra-violet light ...
