Fig 5.4: Oligomeric states <strong>of</strong> Cpn60.2. Using AUC and MS the oligomeric states <strong>of</strong><br />

Cpn60.2 were determined (Adapted from Elsa Zacco, Master’s Thesis 2010). (a) AUC<br />

analysis showing sedimentation coefficient <strong>of</strong> Cpn60.2 in buffer A and buffer 5. (b) MS<br />

analysis showing the various oligomeric states <strong>of</strong> Cpn60.2 present in high salt buffer with<br />

ATP (result obtained by Dr. J Freeke and Dr. J Benesch from the <strong>University</strong> <strong>of</strong> Oxford).<br />
