Abstract
Plasmids may appear in different forms: circular with different degrees of coiling, partially cleaved or linear, and multimeric as concatamers or catenates, Capillary gel electrophoresis (CGE) of plasmid samples allows the determination of plasmid form distribution. Monomeric and dimeric plasmid DNA forms were separated by both CGE and agarose gel electrophoresis (AGE), The pattern of isoform bands from AGE was compared to the corresponding peak pattern from CGE, and differences in the relative mobility of the plasmid forms between the two methods were found, The comparison of AGE and CGE allows the assignment of AGE bands to CGE peaks. Additionally, the different isoforms can now be quantified by CGE. Routine plasmid form analysis by CGE may be automated, allowing easy, fast, and highly reliable quantification. CGE also offers high resolution and the amount of DNA required is very low, Therefore this method is very useful for the analysis of therapeutics based on plasmid DNA during their production, isolation, and formulation (C) 1999 Academic Press.
