Guidelines for sample preparation can be found below. Please note that samples vary dramatically and the conditions (i.e., methods, concentrations, reagents, etc.) must be optimized for each sample type. When considering using mass spectrometric analysis for the first time or when starting a new project, please contact the Facility (Small & Macromolecule OR Peptides & Proteins (proteomics) - Mary Kinsel, PhD.; Stable Isotope - Mandy Rothert, M.S.) with questions/concerns regarding analysis of your samples.
