Thiocarbohydrazide is an osmiophilic reagent. It is used in the OTO staining method (osmium fixed tissue exposed to TCH followed by a second treatment with osmium) to enhance the contrast of all osmophilic components of the cell, especially lipids, which hold the most osmium.

Supplier: Electron Microscopy Sciences

Ruthenium tetroxide is very similar to osmium tetroxide, and is used as a fixation/staining agent for electron microscopy.

(Glyoxaline) C3H4N2 F.W. 68.08 Assay min 99.5% Imidazole is a lipid-enhancing buffer agent. When used with 4% osmium tetroxide solution in the post-fixation of tissue blocks, it produces a prominent electron-opaque staining of lipid droplets with no evidence of diffusion.

Studies show that in order to get good results in positive staining of sections, the removal of cured epoxy (embedding material) as well as the reduced-osmium (fixation materials) from the sections is necessary; especially when double fixation with an Aldehyde and Osmium tetroxide is employed to process specimens for E.M.
We offer a CURED-EPOXY-REMOVER kit, which removes the polymerized resin as well as the reduced-osmium. The structure of the resin free section will remain unchanged.
