How to avoid genomic DNA contamination when isolating mitochondrial DNA?

Greetings! I am trying to isolate mitochondrial DNA from S. cerevisiae while avoiding contamination from genomic DNA. Any and all help is greatly appreciated.

I would suggest that you run a real-time PCR assay with mtDNA and nuclear DNA primer sets. By doing that you will enrich the mtDNA/nDNA and you will be able to verify the purity of your preparation. Then you can run the extracted DNA on an agarose gel and extract only the mtDNA band(s).
