Cytoskeleton electron micrograph
WebMicrotubules are one of the three components of the eukaryotic cytoskeleton and play a central role in many aspects of cell function, including cell division and cell motility. Electron microscopy, of both isolated microtubules and of microtubules in their cellular context, is an essential tool in understanding their structure and function. WebJan 1, 1991 · A general description is given of the various techniques that may be used in ultrastructural studies of the cytoskeleton. Electron microscopy of the cytoskeleton of Dictyostelium discoideum serves as a source of examples illustrating the general effects of detergent treatment and fixation techniques.
