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

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
