title: Purification of vanadium binding substance from the blood cells of the tunicate, Ascidia sydneiensis samea.
abstract: Vanadium binding substance has been partially purified through chromatographies on Sephadex G-25 and SE-Cellulose at pH 2.3. The binding substance was colorless, relatively stable and maintained vanadium ion. The vanadium ion in the substance existed in vanadyl form (VO(IV)). Furthermore, the substance had an apparent affinity for exogenous vanadium ion(V) and contained a reducing sugar.
