WebI want to determine the cellular localization of a protein, hence looking for a protocol to fractionate cell extracts, i.e. cytoplasmic, soluble nuclear extract and chromatin bound fraction. In cell biology, cell fractionation is the process used to separate cellular components while preserving individual functions of each component. This is a method that was originally used to demonstrate the cellular location of various biochemical processes. Other uses of subcellular fractionation is to provide an … See more Tissue is typically homogenized in a buffer solution that is isotonic to stop osmotic damage. Mechanisms for homogenization include grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and See more • Cell disruption Media for cell separation by density: • Percoll • Ficoll See more This step may not be necessary depending on the source of the cells. Animal tissue however is likely to yield connective tissue which must be removed. Commonly, … See more Purification is achieved by differential centrifugation – the sequential increase in gravitational force results in the sequential separation of … See more
