In this study, we demonstrate that Trypanosoma cruzi epimastigotes previously grown in LIT medium supplemented with 20 mM galactose and exposed to sub-lethal concentrations of hydrogen peroxide (100 μM) showed two-fold and five-fold viability when ...

Flow Cytometric Analysis of the Cell Cycle in Transfected Cells Without Cell Fixation
We describe a simple and rapid protocol for the flow cytometric analysis of the cell cycle in transfected cells using a green fluorescent protein anchored in the intracellular membranes of the endoplasmic reticulum (ER-GFP) as a transfection marker.

Application of flow cytometry to determine differential redistribution of cytochrome c and Smac/DIABLO from mitochondria during cell death signaling. [PDF]
Mitochondrially mediated apoptosis is characterized by redistribution of proteins from mitochondria to cytoplasm following permeabilization of the outer mitochondrial membrane.

Rapid quantitative procedure for removing cholesterol from butter fat
Cholesterol is rapidly and quantitatively removed from butter fat by passage of the fat in hexane or benzene solution over a column of Celite impregnated with an aqueous solution of digitonin.

Rapid enrichment of mitochondria from mammalian cell cultures using digitonin
We describe here a simple method to enrich mitochondrial fractions from mammalian cells for downstream analyses in the lab. Mitochondria purification involves cell lysis followed by separation of the organelles from the rest of the cellular components ...

Nuclear entry of hepatitis B virus capsids involves disintegration to protein dimers followed by nuclear reassociation to capsids. [PDF]
Assembly and disassembly of viral capsids are essential steps in the viral life cycle. Studies on their kinetics are mostly performed in vitro, allowing application of biochemical, biophysical and visualizing techniques.

Separation of the Inner and Outer Mitochondrial Membrane in HeLa Cells
Mitochondria are organelles that have important functions in oxidative phosphorylation, fatty acid oxidation and apoptosis signaling. They have two distinct membranes, outer membrane (OM) and inner membrane (IM).

Studies on the fractionation by digitonin of chloroplast membranes [PDF]
11. The basic action of digitonin was to separate the grana thyla- koids from the intergrana thylakoids [Z]. Thus the heavy fraction (10 000 X g pellet, enriched in photo- sytem II) consisted mostly of grana, while the light fraction (10 000 X g supernatant, enriched in photo- system I) consisted mostly of intergrana membranes.
