Compositions in which organo-mercurial moieties are bound to glass or other inorganic substrates are useful in separating sulfhydryl-containing compounds from mixtures with other compounds, e.g., by affinity chromatography.

Organo-mercurial materials

A stabilized composition comprising a solution of a radiolabeled compound and a diethylenetriamine is described. Preferred diethylenetriamines include, N,N-bis(2-aminoethyl) dithiocarbamic acid, di(2-dithiocarbamyl-ethyl) amine, and salts thereof.

Composition and method for stabilizing radiolabeled compounds using

A method of stabilizing a solution of a radiolabeled compound comprising adding to such solution a compound having a substantially insoluble backbone, to which has been bound a quaternary ammonium group; or a water soluble primary, secondary or tertiary aliphatic amine. The present invention also includes a solution of a radiolabeled compound maintained in contact with such a compound, and as an article of manufacture, a sealed vial containing such a solution.

Method, composition and kit for stabilizing radiolabeled compounds

A method and kit for stabilizing solutions of radiolabelled compound by the use of insoluble quaternary ammonium containing compounds. Also described are novel insoluble compounds having quaternary ammonium and sulfide groups for use in the present invention.
