Application

Allantoin may be used as an analytical reference standard for the quantification of the analyte in biological samples using different chromatography techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Biochem/physiol Actions

Purine metabolite via the uric acid pathway. Uric acid also reacts with free radicals to produce allantoin, thus allantoin may be a useful biomarker for oxidative stress.

Packaging
