Abstract
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%.
摘要
对鸟苷三磷酸（GTP）和5'-四磷酸鸟苷的商业样品进行了分析，无论是否预先用碱性磷酸酶处理，均在Hypersil ODS柱上通过高压液相色谱法进行分析。结果显示，根据样品不同，存在不同含量的5',5"'-P1,Pn-三磷酸、四磷酸和五磷酸二鸟苷，但通常比例约为0.3%。
