Mitochondria isolation - (Jan/23/2006 )

My questions:

1. Which method can be used for getting high purity of mitochondria from cells beside the kit.
2. which marker can be choosed to check the purity of mitochondria.
Thanks

My suggestions:

1. Differential centrifugation (old school...)
2. DiOC6(3) at low contration or MitoTracker, by flow cytometry (quantitative)
