    摘要: This invention relates to the staining of cells, and in particular provides a novel reagent for the detection, for example, of DNA (deoxyribonucleic acid) and polysaccharides by electron microscopy.A reagent for staining cells in accordance with the present invention comprises an aqueous solution of a nitrido-bridged complex of osmium or ruthenium and having the general formula:[M.sub.2.sup.IV N(NH.sub.3).sub.8-2x X.sub.5-y (H.sub.2 O).sub.x ]Y.sub.y.where M represents either Os or Ru, X and Y are the same or different anions selected from nitrate, halide and pseudohalide, x is 0 or 1 and y is 2 or 3.
