Description: 4800 Proteomics Analyzer (Sciex)
Technical specifications: Mass spectrometer equipped with a matrix-assisted laser desorption/ionization (MALDI) source, using a Nd:YAG 200-Hz laser, and two time-of-flight mass analyzers in tandem with a high-energy collision-induced disociation (CID) chamber for ion fragmentation. It has a variable ion path length to accomodate MS linear, MS reflector and MS/MS acquisition modes.
Applications: Determination of molecular masses of peptides, proteins and other biomolecules. Protein identification by peptide fingerprint or peptide fragmentation. Shotgun quantitative proteomics analyses by isotopic labeling and LC-MALDI workflows.
