Mass Spectrometry

The expanding field of proteomics involves many unique requirements, particularly in terms of specific reagent needs for Mass Spectrometry - Sigma understands and meets these Mass Spectrometry needs. For routine MALDI Mass Spectrometry calibration, we offer ProteoMass MALDI Calibration Kits, as well as individual highly purified ProteoMass MALDI matrices and a wide range of well-recognized, prequalified MALDI Mass Spectrometry calibrants. Trypsin, Proteomics Grade, offers superior sequence coverage while eliminating ambiguous autolytic MALDI peaks. The Trypsin Profile IGD kit enables fast, efficient, completed digestion from PAGE to MALDI. The NEW Protease Profiler provides four proven alternative proteases, in addition to trypsin, for protein digest prior to Mass Spectrometry. The ProteoMass Guanidination Kit enables dramatic improvement of MALDI Mass Spectrometry sensitivity. Through our targeted selection of kits, calibrants, and matrices for Mass Spectrometry, Sigma is proud to meet your Mass Spectrometry reagent needs!
