Abstract

Many types of studies require the localization of a protein to, or isolation of enriched protein from a specific cellular compartment. Many protocols in the literature and from commercially available kits claim to yield pure cellular fractions. However, in our hands, the former often do not work effectively and the latter may be prohibitively expensive if a large number of fractionations are required. Furthermore, the largely proprietary composition of reagents in commercial kits means that the user is not able to make adjustments if, for example, a particular component affects the activity of a protein of interest. The method described here allows the isolation of purified proteins from three cellular fractions: the cytosol, membrane-bound organelles, and the nucleus. It uses gentle buffers with increasing detergent strength that sequentially lyse the cell membrane, organelle membranes and finally the nuclear membrane.•Quick, simple to replicate or adjust; this method does not require expensive reagents or use of commercial kits•The protocol can be applied to tissue samples or cultured cells without changing buffer components•Yields purified fractions of cytosolic, membrane bound and nuclear proteins, with the proper distribution of the appropriate subcellular markers: GAPDH, VDAC, SERCA2 and lamin A/C.

  • Since the discovery of SUCNR1/GPR91 in 2004, it became evident that succinate plays a regulatory signaling role in the formation of adaptive mechanisms of tolerance to ischemia/hypoxia at cellular, tissue, and organismic levels.

    “In 2004, when the highly specific succinate receptor SUCNR1/GPR91 was discovered, it became evident that succinate plays a regulatory signaling role in the formation of adaptive mechanisms of tolerance to ischemia/hypoxia at the cellular, tissue, and organismic levels [59,99,100,101].”

    From Protective Effects of PGC-1α Activators on Ischemic Stroke in a Rat Model of Photochemically Induced Thrombosis (2021) · cites this paper as [100]

    The Method details passages describe subcellular protein fractionation, including work with isolated rat hearts, but do not address succinate signaling or tolerance to ischemia or hypoxia. Searches for SUCNR1/GPR91, the 2004 receptor discovery, and succinate-mediated adaptation found no relevant passage in our copy. (LLM, conf=0.76)

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.
