Membrane Extracts from Plant Tissues

Abstract

The comparison of isolated plant cell membranous enclosures can be hampered if their extraction method differs, e.g., in regard to the utilized buffers, the tissue, or the developmental stage of the plant. Thus, for comparable results, different cellular compartments should be isolated synchronously in one procedure. Here, we devise a workflow to isolate different organelles from one tissue, which is applicable to different eudicots such as Medicago x varia and Solanum lycopersicum. We describe this method for the isolation of different organelles from one plant tissue for the example of Arabidopsis thaliana. All compartments are retrieved by utilizing differential centrifugation with organelle-specific parameters.
