Abstract: We recently reported a new method to isolate functionally intact mitochondria from cell culture and small tissue samples (Schmitt et al., Anal Biochem 443(1):66-74, 2013). This method comprises a semi-automated cell rupture, termed pump controlled cell rupture system (PCC), which can be precisely adjusted to the specific cellular source of isolation and which can be tightly controlled (Schmitt et al., Anal Biochem 443(1):66-74, 2013). Here we provide a detailed hands-on protocol of this PCC method which results in an efficient cell breakage but preserving the mitochondrial integrity. Upon subsequent purification steps, the obtained mitochondrial fraction meets the quality and purity required for molecular analyses, e.g. proteomic comparisons, as well as for biochemical analyses, e.g. determination of diverse enzymatic activities.
