A facile method for the preparation of N6-substituted ATP-Sepharose

Abstract
The attachment of 6-methylsulfonylpurineribose 5'-triphosphate to AH-Sepharose 4B as a facile method for the preparation of ATP-Sepharose is described. This reaction is compared to the coupling of 6-chloropurineriboside 5'-triphosphate as well as N(6)-aminocaproyl-ATP. An improved synthesis of purineriboside 5'-phosphates which does not require purification by column chromatography is also described.
