A scaleable method for the liquid-phase separation of plasmid DNA from RNA ... Another potential application is to the isolation of RNA; preliminary work indicates that potent compaction agents ...

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.

Scientists who have described in a new study the step-by-step details of a bacterial ... of DNA – known as a DNA guide – to set off events that recruit another protein to chop up the plasmid.

For example, many antibiotic-resistance genes spread through plasmid transfer between bacteria. However, bacteria also have numerous defense mechanisms aimed at eliminating any foreign DNA ...

The GENE PREP has protocols for DNA purification and extraction from tissues, cells, plants and plasmid preps.
