More Details

INOSINE is a purine nucleoside formed from Ribose and Hypoxanthine that can be found in most animal tissues and fluids. Inosine is most often found in tRNAs and is important for proper translation of the genetic code. It may play a role in cancer immunometabolism. It is degraded via the purine degradation pathway, first by purine nucleoside phosphorylase to hypoxanthine, then to xanthine by xanthine oxidase and then finally to uric acid by further action of xanthine oxidase.

Simple, direct and high-throughput assays for measuring inosine find wide applications in research and drug discovery. BioAssay Systems’ inosine assay kit uses a single Working Reagent that combines the enzyme reactions and color reaction in one step. The change in fluorescence intensity at λex/em = 530/585 nm is directly proportional to inosine concentration in the sample.
