0.5% stabilised aqueous solution. Ruthenium tetroxide is very similar to osmium tetroxide and is used as an EM fixative/stain. It gives excellent staining of saturated and unsaturated polymer materials with improved image contrast. RuO4 also has a stabilising effect against electron beam damage of material films. Note: penetration of ruthenium tetroxide into tissue is poor. Store at 4°C.
