(Peabody, Mass.) JEOL USA has produced a new MALDI imaging technical applications note that describes the unique analytical process for a variety of biological and organic samples. MALDI imaging is a powerful mass spectrometry technique available with JEOL’s MALDI Imaging SpiralTOF. It is used to assess the distribution of proteins, peptides, lipids, drugs, and metabolites in tissue specimens, as well as compound distribution in organic materials. MALDI is an acronym for matrix-assisted laser desorption/ionization mass spectrometry.
High-resolution mass spectra are collected for the entire image in each of the examples ranging from lipids in mouse brain tissue to Organic Electroluminescent Panels and laser desorption ionization of ballpoint inks.
The full-color applications note is available for free download at http://go.jeolusa.com/MALDI. More than a dozen application-specific notes are also available on specific MALDI imaging applications on the JEOL website at www.jeolusa.com.
