Mark Lowenthal

Mark’s research activities at NIST include the measurement of amino acids and proteins in human serum.  He has developed new methods for quantification of human cardiac troponin I in serum involving immunoassay development and multiple-reaction monitoring mass spectrometry, and performed absolute quantification measurements of amino acids in plasma.  These activities have led to the production or certification of several SRMs. A separate focus is on development of techniques for characterization of proteins and small molecules bound to nanoparticles.  Mark has co-authored more than a dozen peer-reviewed publications.
