To many investigators, cell fractionation is a tool, which provides them with a preparation of a given subcellular component, endowed with functional properties that form the matter of sophisticated studies. However, the complexity of such subcellular preparations is not always clearly recognized, ...
Cells contain multiple organelles, so the fractionation process must be able to separate and isolate each organelle of interest. There are two common methods scientists use to find a particular organelle: Density gradient centrifugation Differential centrifugation Earlier in this lesson it was said ...

In this chapter, we describe how the different compartments can be selectively isolated by a combination of centrifugation and disruption techniques. Fractionation of the cells into subcellular compartments enables protein enrichment and is essential to accurately determine the localization of specific ...

and for resolving this homogenate by differential centrifugation into four fractions containing mainly but not exclusively (1) nuclei and large cell debris; (2) mitochondria and other large granules; (3) small granules, designated microsomes (Claude, 1943), which were found later to derive largely...
Cell fractionation kits are optimized for stepwise separation, enrichment, and extraction of proteins from different cellular fractions, including cytoplasmic, membrane, nuclear, chromatin-bound, and cytoskeletal proteins in 1–3 hours. Our organelle kits are optimized for...
Cellular fractionation and subsequent protein localization is a very interesting approach for EE evaluation. Although this methodology has mainly been explored forsubcellular localizationofnucleic acidsusingqPCR(Akita et al., 2004;Hama et al., 2006), its basis can also be applied to protein localizatio...
As in the case of many biological separation procedures, cell fractionation is a time-consuming process. The homogenates must be centrifuged for relatively long periods of time, depending on the organelle that is being isolated, the centrifugation is repeated and re-suspended in fresh re-suspension...
A 4-h incubation with EdU followed, after which the cells were fixed, stained with Apollo®567, and visualized under fluorescence microscopy for analysis. Nuclear-Cytoplasmic fractionation For nuclear-cytoplasmic separation, cells were collected and fractionated using a Nuclear/Cytosol Fractionation Kit...
