Parallel labelling of non-dialyzable components of rabbit urine following 75SeO4 and 35SO4 injection

Abstract

Following the intravenous administration of Na₂⁷⁵SeO₄ and Na₂³⁵SO₄ in rabbits, the non-dialyzable solids of urine were labelled with ³⁵S and ⁷⁵Se in a parallel manner both on BaCO₃-fractionated specimens and when chondroitin sulfate A and C were isolated by glass-paper chromatography. ⁷⁵Se-labelled selenate may be a useful adjunct to the tools currently available for the metabolic studies of sulfomucopolysaccharides.
