WitrynaSubcellular fractionation and protein enrichment are important methods in the rapidly growing field of proteomics. Isolation of subcellular fractions and concentration of … Witryna7 sty 2024 · If you know what different organelles look like in cells, you can figure out which are the largest e.g. ribosomes are tiny compared to chloroplasts, and the nucleus is massive. From that relative order of organelles, you can figure out the order in which they will come out in a pellet. This assumes that the centrifugation gets faster each …

WitrynaSome diseases can be traced back to organelle lack / malformation. For example, inclusion-cell (I-cell) disease occurs due to a defect in the Golgi. In order to mark enzymes that should be sent to lysosomes to help degrade unwanted molecules, the Golgi has to bind them with a mannose 6-phosphate tag, like a shipping label.
