PIXE-PESA Analysis to Determine Metalloprotein Stoichiometry Research Advisor: Dr. Paul DeYoung While approximately a third of all proteins are metalloproteins, their stoichiometric ratios are still largely unknown. Current elemental analysis procedures are capable of determining which metals are in a protein, but it is difficult to determine how many. To address this, an ion beam … Continue reading "Elizabeth Lindquist – 2015"
