WebNov 15, 2024 · Organelle subcellular fractionation consists of two major steps: disruption of cellular organization and fractionation of the homogenate into different organelle populations [1, 4]. Traditional organelle proteomics seeks to extract proteins from these fractions; however, we aim to extract and analyze nucleic acids from each fraction [ 5 ]. To get to the content inside of something, you have to open it. Cells are no different. Detergents allow the cell membrane to be opened so that the contents inside the cell can be obtained. Detergents disrupt cellular membranes because they can interact with both membranes and parts of the cell that are soluble in … See more Cell homogenates are separated into fractions by spinning them super-fast in a process called centrifugation. If you have ever ridden an anti-gravity carnival ride, then you understand … See more The way cell fractions are collected will depend on the liquid in which the cell fractions are centrifuged.
