一般說明

Osmium tetroxide for microscopy can be used to visualize unsaturated lipids. A part of the lipids is immediately blackened by the influence of osmic acid solution. The immediate black coloration results from the -C=C- double bond of the unsaturated fatty acid. The fatty acids that are made brownish at first can be blackened by treatment with 60-70% alcohol. For electron microscopy or semithin sectioning the glutardialdehyde-fixed specimens are post-fixed with osmium(VIII) oxide. Lipid inclusions appear black on a yellow to brown background. It is an IVD / CE registered product. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.

Autophagy, 16(3), 501-511 (2019-06-18)
Chondrogenesis is accompanied by not only cellular renovation, but also metabolic stress. Therefore, macroautophagy/autophagy is postulated to be involved in this process. Previous reports have shown that suppression of autophagy during chondrogenesis causes mild growth retardation. However, the role of

The propagation of electrical impulses along axons is highly accelerated by the myelin sheath and produces saltating or "jumping" action potentials across internodes, from one node of Ranvier to the next. The underlying electrical circuit, as well as the existence
