A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

A scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...

A restriction map of the 5.3 kb insert is prepared. The recombinant plasmid is digested with the enzymes listed above in single digests, and then several combinations of enzymes are tested in double ...

Conjugation is a form of horizontal gene transfer that allows the exchange of genetic material between two organisms or cells ...

Plasmids are used in molecular biology to build gene circuits because they are easy to modify and can boost gene expression. However, plasmid copy numbers can fluctuate, causing inconsistent gene ...

WuXi Biologics has launched the E coli expression system, EffiX, designed to enhance the production of recombinant proteins and plasmid DNA (pDNA). The worldwide market for microbial-derived products ...

Imunon has reported new immunogenicity and safety data from its proof-of-concept Phase I trial’s ongoing analyses of the IMNN-101 DNA plasmid vaccine. The investigational vaccine, based on the ...
