Application

Xanthine-agarose is used for protein chromatography, affinity chromatography and specialty resins. Xanthine-agarose has been used to purify and determine molecular properties of urate oxidase from Chlamydomonas reinhardtii. Xanthine-agarose has also been used to determine physicochemical properties and states of sulfhydryl groups of uricase from Candida utilis.
