Cohen, Theodore M.; Rohs, Amanda E.; Lefebvre, Brian G. – Biochemistry and Molecular Biology Education, 2008
A simple in class laboratory illustrating the principles of ion exchange chromatography as a bioseparation technique is described. A protein's isoelectric point as a driving force for ion exchange chromatography is easily demonstrated by using combinations of proteins with natural color or fluorescence, such as DsRed2, enhanced green fluorescent…
