An SDS–PAGE Examination of Protein Quaternary Structure and Disulfide Bonding for a Biochemistry Laboratory  Jennifer L. Powers, Carla S. Andrews, Caroline C. St. Antoine, Swapan S. Jain, and Vicky L. H. Bevilacqua
In this experiment, students use sodium dodecyl sulfatepolyacrylamide gel electrophoresis (SDSPAGE) and -mercaptoethanol (ME) to determine preliminary information about protein quaternary structure. This experiment gives students a better understanding of protein subunit composition and the forces responsible for the stability of quaternary structure. The experiment can be accomplished in one three-hour laboratory period.
