The interest in purifying injectable-grade plasmid DNA has increased with the development of gene therapy and DNA vaccination technologies. In this paper we develop a method for purifying a 4.8 kb plasmid based on chromatographic processes. An NaCl gradient was optimized on a Q Sepharose 1 column an

✦ Synopsis
Isolation of ultrapure supercoiled plasmid-DNA using preparative electrophoresis
A large-scale preparative polyacrylamide gel electrophoresis (PAGE) system for the isolation of high-purity supercoiled plasmid-DNA is described. This method should prove suitable for the isolation of large DNA molecules, either plasmid or linear DNA, that is required for the production of transgenic animals, for instance. The efficiency of the method is illustrated by the isolation of the gene for the green fluorescent protein, cloned into a mammalian expression vector and used for transfection of eukaryotic cells.

## Abstract ## Background It is well known that the success of gene transfer to cells and subsequent expression is strictly affected by the vector manufacturing process. Several challenges encountered in the gene therapy field have emphasized the need for the development of novel platforms that al
## Abstract A density gradient apparatus was used to examine the separation of different physical forms and sizes of DNA. A gradient of sucrose was used to stabilize thermal convection during electrophoresis in the column (2.2 cm in diameter). Linear polymers were added to the density gradient and
