Abstract:
Two-dimensional neutral/neutral agarose gel electrophoresis (2D-AGE) has been employed for nearly two decades in the analysis of replication and maintenance processes of animal mitochondrial DNA, but the method's potential has not been fully exploited. Here, we describe the various steps involved in this technique, from DNA isolation, to two-dimensional neutral/neutral agarose gel electrophoresis (2D-AGE), Southern hybridization and interpretation. We also provide examples of the applicability of 2D-AGE to investigate the different features of mtDNA maintenance and regulation.

Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...
