Guanine-15N5

Guanine-15N5 is intended for use as an internal standard for the quantification of guanine (Cay-34248) by GC- or LC-MS. Guanine is a purine base. It forms complementary base pairs with the pyrimidine cytosine in DNA and RNA. Guanine can be linked to ribose via a beta-N9-glycosidic bond to form the purine nucleoside guanosine (Cay-27702), which can be phosphorylated to guanine-based purines that have numerous roles in intracellular signal transduction.Formal Name: 2-(amino-15N)-1,7-dihydro-6H-purin-6-one-1,3,7,9-15N4.
