The ruthenium red cation is a complex of ruthenium with ammonia in which there are two 0x0-bridges:
Its chloride form is widely used in histochemical studies because its selective reaction with mucopolysaccharides (2)(3).
On this basis, the availability of a radioruthenium labelled complex is of significant value fop the investigation of that type of interaction.
The labelled ruthenium red was prepared as follows: 1 mCi '03RuClj (1.55 mg of Ru in 4 N RC1) was brought to 0.25 N HC1 in a

Ruthenium-103 red has been used previously to detect nanogram quantities of glycosaminoglycans after they have been separated by electrophoresis on cellulose diacetate. We have applied the critical electrolyte principle to the binding of this dye to polyanions. This eliminates interaction with nucle
Ru-atoms (0.5-1.5 g) have been generated by electron bombardment and, in separate experiments, were co-condensed at 77 K with excess of 2,3-dimethylbutadiene or 1,3-or 1,4-~yclohexadiene. The complexes Ru(CO)(q 4-C,H,,), (1) and Ru(CO)(r;14-C,H,), (2), respectively, have been isolated in 25-30% yiel
