Prediction of selectivity for the separation of double-stranded DNA fragments in electrophoresis

Abstract

The electrophoretic resolution (selectivity) of double-stranded DNA (dsDNA) restriction fragments is studied for different organisms (phi X174, lambda phage, and pGEM-3 plasmids) by various separation and detection methods. The selectivity can be predicted by plotting the difference in chain length over their average chain length (base pair difference/average base pair magnitude of delta bp/Ave.-bp) against each DNA fragment pair. Experimental conditions and the nature of the DNA can influence the predicted results.
