Protein/Peptide Mass Determination

The Protein Chemistry Laboratory performs mass analysis of proteins and peptides using matrix-assisted, laser-desorption ionization (MALDI) methods and time-of-flight (TOF) mass analysis and Electrospray Ion Trap mass spectrometry.  WE DO NOT PERFORM ANALYSIS OF POLYNUCLEOTIDES OR OTHER BIOPOLYMERS.  We recommend that you contact the Laboratory for Biological Mass Spectrometry in the Department of Chemistry at Texas A&M University for non-protein mass spectrometric analyses.
