Storage/Stability
The decomposition of solutions in 0.5 M H2SO4 or in 10 M NaOH is less than 10% after one hour at 100 °C. Stock solutions of at least 10 mM in sodium hydroxide can be stored at 2-8 °C for one week.
Xanthine is a catabolic product of purine nucleotide metabolism. It is degraded by xanthine oxidase to uric acid. Natural sources of xanthine or its derivatives include animal organs, yeast, potatoes, coffee beans,and tea.2 Xanthine and xanthine oxidase are used to generate superoxide radicals used to measure the activity of superoxide dismutase.
