| Application: | Xanthine has been used as a substrate for the determination of xanthine oxidase (XOD) inhibitory activity. It has also been used in the following systems: • yeast culture • human cell line culture • recombinant viruses cloned as bacterial artificial chromosomes in Escherichia coli |
| Biochem/physiol Actions: | Xanthine and xanthine oxidase are used to generate superoxide radicals to measure the activity of superoxide dismutase. |
| Features and Benefits: | • Tested for trace metal content (fuller details in Properties section and on Specification Sheet) • Tested for trace sulfate content (fuller details in Properties section and on Specification Sheet) |
| General description: | Xanthine is a purine that can be produced in the purine metabolic pathway via different precursors: • Guanine deamination by guanine deaminase • Hypoxanthine conversion by xanthine oxidoreductase |
| General description: | Xanthine or its derivatives are naturally present in animal organs, yeast, potatoes, coffee beans, and tea. |
