WebMALDI is “Matrix-Assisted Laser Desorption Ionization”. It is a soft ionization technique that strikes large molecules with laser energy into minimal ion fragments. MALDI helps in the analysis of biomolecules such as DNA, proteins, peptides, saccharides, and large organic molecules like polymers, dendrimers, and other macromolecules. WebOligomeric products of chitosan hydrolysis were not found, which was confirmed by MALDI-TOF analysis.

In mass spectrometry, matrix-assisted laser desorption/ionization (MALDI) is an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal fragmentation. It has been applied to the analysis of biomolecules (biopolymers such as DNA, proteins, peptides and … See more The term matrix-assisted laser desorption ionization (MALDI) was coined in 1985 by Franz Hillenkamp, Michael Karas and their colleagues. These researchers found that the amino acid alanine could be ionized more easily if it was … See more There are several variations of the MALDI technology and comparable instruments are today produced for very different purposes. From … See more Biochemistry In proteomics, MALDI is used for the rapid identification of proteins isolated by using gel electrophoresis: SDS-PAGE, size exclusion chromatography, affinity chromatography, strong/weak ion exchange, isotope … See more • Ragoussis, J.; Elvidge, G.
