Photoaffinity reagents radiolabeled

Such an approach to the preliminary evaluation of photoaffinity reagents goes one step beyond the reversible binding experiments discussed earlier. It is a useful approach in that, like competitive binding experiments, radiolabeled ligand is not required and therefore many potential reagents may be screened. However, many pitfalls severely reduce its utility. 

Several radiolabeled photoaffinity reagents including 8-azido adenosine phosphates. Radiolabeled heterobifunctional reagents...
