Here we present protocols for detergent-free homogenization of cultured mammalian cells based on nitrogen cavitation and subsequent separation of cytosolic and membrane-bound proteins by ultracentrifugation. This method is ideal for monitoring the partitioning of peripheral membrane proteins between soluble and membrane fractions.

Early endosome functions depend on F-actin polymerization. Here, we describe a microscopy-based in vitro assay that reconstitutes the nucleation and polymerization of F-actin on early endosomal membranes in test tubes, thus rendering this complex series of reactions amenable to biochemical and genetic manipulations.
FAQs
Their relative localization provides a spatial view of how intracellular cargo moves through successive membrane compartments. Rab5 signals early endosomal organization, Rab9 highlights transport associated with late endosomes and the trans-Golgi network, and LAMP1 indicates lysosomal membrane identity. Examining these patterns together helps researchers assess compartment organization and cargo-processing progression.
Each marker reports a different stage or destination within the endosomal and lysosomal system, so a single marker provides only limited context. Combined analysis allows researchers to compare early endosomes, late-endosome-to-trans-Golgi transport, and lysosomal compartments in the same cellular system. This broader view supports interpretation of membrane trafficking pathways and organelle relationships.
Altered localization or relationships among the markers can suggest disrupted organization of endosomal or lysosomal pathways. For example, differences in the expected distribution of early-endosomal, late-endosomal, or lysosomal signals may reveal abnormalities in cargo progression or compartment formation. Such observations are relevant when investigating cellular disease linked to defective vesicular transport.
Colocalization analysis compares the spatial distribution of marker signals within cells rather than examining each protein in isolation. The resulting relationships help characterize whether cellular regions share features associated with particular trafficking compartments or reflect transitions between them. This approach can therefore support studies of endosome maturation, lysosome formation, and membrane-system organization.
A typical study labels the selected markers using immunostaining or another fluorescence-based detection approach, images the cells by fluorescence microscopy, and compares the resulting signal patterns. Researchers then examine marker localization and colocalization to characterize compartment identity and trafficking organization. The workflow can be adapted to investigate normal pathways or suspected transport defects.
This panel is useful when the research question concerns more than one stage of intracellular membrane trafficking. It can help distinguish early endosomal organization from late-endosome transport and lysosomal compartments, while also supporting studies of organelle formation and cargo-processing pathways. Researchers may apply it when comparing cellular conditions associated with altered vesicular transport.
