Ruthenium tetroxide is very similar to Osmium tetroxide, and is used as a fixation/staining agent for electron microscopy. Ruthenium tetroxide offers excellent staining of saturated and unsaturated polymer materials as well as stabilizing thin sections under the bombardment of the electron beam.
NOTE: Penetration of ruthenium tetroxide into the tissue is poor.
