Isolation of Mitochondria, Their Sub-Organellar Compartments, and Membranes

Methods Mol Biol. 2017:1511:83-96. doi: 10.1007/978-1-4939-6533-5_7.

Abstract

Mitochondria are the sites of a diverse set of essential biochemical processes in plants. In order to facilitate the analysis of these functions, this chapter presents protocols for the isolation of intact mitochondria from a range of plant tissues as well two workflows for fractionation into their four subcompartments; the inner and outer membranes and the two aqueous compartments, the inter membrane space and matrix. Protocols for the assessment of mitochondrial integrity and purity through enzymatic function and suggestions of commercially available compartment marker antibodies are provided.

Keywords: Arabidopsis; Intermembrane space; Matrix; Mitochondria; Protoplast; Solanacea; Subfractionation.
