Highly photoresistant and selective chemosensors have been prepared using acridone as fluorescent label in combination with monoclonal antibodies. Highly photoresistant and selective chemosensors have been prepared using acridone as fluorescent label in combination with monclonal antibodies. These monomers were coupled in solution using BOP activation of the carboxy terminus to form (1→ 5)-amide linked dimers of sialyl amino ...
