Isolation of mitochondria-associated membranes and mitochondria from animal tissues and cells

Abstract

Many cellular processes require the proper cooperation between mitochondria and the endoplasmic reticulum (ER). Several recent works show that their functional interactions rely on dynamic structural contacts between both organelles. Such contacts, called mitochondria-associated membranes (MAMs), are crucial for the synthesis and intracellular transport of phospholipids, as well as for intracellular Ca(2+) signaling and for the determination of mitochondrial structure. Although several techniques are available to isolate mitochondria, only few are specifically tuned to the isolation of MAM, containing unique regions of ER membranes attached to the outer mitochondrial membrane and mitochondria without contamination from other organelles (i.e., pure mitochondria). Here we provide optimized protocols to isolate these fractions from tissues and cells. These procedures require 4-5 h and can be easily modified and adapted to different tissues and cell types.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
