           Tandem ion trap / ion mobility / time-of-flight mass spectrometric methods were used to examine dynamic protein unfolding and folding as ions were   
           stored in the ion trap. In addition ion mobility was used to examine dissociation patterns of different protein ion conformers and to monitor conformers      
           observed after dissociation of protein ions.
