✦ Synopsis

Commercial samples of GTP and guanosine 5'-tetraphosphate were analyzed, with or without previous treatment with alkaline phosphatase, by high-pressure liquid chromatography on a Hypersil ODS column. They showed the presence of diguanosine 5',5"'-Pl,Pn-tri, tetra-, and pentaphosphates in varying amounts depending on the sample, but usually in proportions of around 0.3%.
