Guanine-15N5 is intended for use as an internal standard for the quantification of guanine by GC- or LC-MS. Guanine is a purine base.[1] It forms complementary base pairs with the pyrimidine cytosine in DNA and RNA. Guanine can be linked to ribose via a β-N9-glycosidic bond to form the purine nucleoside guanosine , which can be phosphorylated to guanine-based purines that have numerous roles in intracellular signal transduction.2,3

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。
