The composition of 20S mouse proteasome complexes isolated from mice heart, kidney, liver, lung, thymus and spleen was compared using quantitative mass spectrometry. Significant variety was observed in hybrid classes of immunoproteasomes which may have implications for the use of proteasome targeted inhibitors.

Peptide Identification Using Tandem Mass Spectrometry

Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...
