title: Chemical synthesis of nucleoside-gamma-[32P]triphosphates of high specific activity.
abstract: A simple chemical procedure for the preparation of four common ribonucleoside 5-gamma-[32P]triphosphates of high specific activity (up to 10 Ci/mmole) based on the condensation of orthophosphoric acid with the corresponding nucleoside 5-diphosphate in the presence of ethyl chloroformate as well as the methods of purification and identification of the products are described.
