the 28 kda protein from calf brain membranes was also eluted from the affinity column by amp and 2',5'-dideoxyadenosine , but at a concentration higher than that at which adenosine eluted the protein , but n6- ( r-phenylisopropyl ) adenosine , 5'-n-ethylcarboxamidoadenosine , adp , atp , gtp , nad+ , cyclic amp and inosine failed to elute the protein at concentrations up to 1 mm .
