Metrologically Traceable Quantification of Three Apolipoprotein E Isoforms in Cerebrospinal Fluid Andy Hoofnagle University of Washington Andy Hoofnagle, MD, PhD (Presenter) University of Washington Presenter Bio: Dr. Hoofnagle's laboratory focuses on the precise quantification of recognized protein biomarkers in human plasma using LC-MRM/MS. In addition, they have worked to develop novel assays for the quantification of small molecules in clinical and research settings. His laboratory also studies the role that the systemic inflammation plays in the pathophysiology of obesity, diabetes, and cardiovascular disease.
