Ruthenium Red Staining of Chromatin in Epon Sections


For a long time, the ammoniated ruthenium oxychloride “ruthenium red” (today formulated [1, 2] as [(NH3)5 R u •O • Ru (NH3)4 O • Ru (NH3)5]6+ • Clg), has been used as a microscopic test for pectins [2, 3]. Several applications of this contrasting agent for electron microscopic detection of acid polysaccharides and proteoglycans have been stud­ ied [4-10… (More)
