7-Methylguanosine-d3 is intended for use as an internal standard for the quantification of 7-methylguanosine by GC- or LC-MS. 7-Methylguanosine is a methylated form of the purine nucleoside guanosine . It is an RNA modification that is present in the 5’-terminal cap of mRNA, where it promotes translation, as well as in tRNA, where it stabilizes the tRNA structure.1,2 7-Methylguanosine has been used as a substrate to measure the activity of purine nucleoside phosphorylase (PNP).3 Urinary 7-methylguanosine levels are decreased in patients with prostate cancer.1
