Wang, Sheila C.; Zamble, Deborah B. – Biochemistry and Molecular Biology Education, 2006
A practical laboratory experiment is described that illustrates the application of fluorescence resonance energy transfer to the study of protein-ligand binding. The affinities of wild-type and mutant human carbonic anhydrase II for dansylamide were determined by monitoring the increase in ligand fluorescence that occurs due to energy transfer…

Clarke, Ronald J.; Oprysa, Anna – Journal of Chemical Education, 2004
The aim of the mentioned experiment is to aid students in developing tactics for distinguishing between signals originating from fluorescence and light scattering. Also, the experiment provides students with a deeper understanding of the physicochemical bases of each phenomenon and shows that the techniques are actually related.

Hilosky, Alexandra; Sutman, Frank; Schmuckler, Joseph – Journal of Chemical Education, 1998
Reports on a series of studies related to seeking a more effective role for laboratory experiences in science instruction. The study addressed the status of laboratory-based instruction in chemistry at the beginning college level. This study should be of value in the continual search to seek effective means of reforming beginning college-level…
