Matrix-assisted laser desorption—ionization compositional analysis

After device construction, structural and functional analysis are critical. One might argue that only the second issue matters, but structural data often give insights into why devices perform suboptimally, and provide important clues about how to improve device function. We routinely use protein analytics (matrix-assisted laser desorption-ionization mass spectroscopy, amino acid composition analysis, gel electrophoresis, Western blotting, circular dichroism, vari-...

Other techniques, such as capillary electrophoresis (CE) and matrix-assisted laser desorption ionization (MALDI) mass spectrometry, provide qualitative analyses-often with greater speed and sensitivity. " Nevertheless, AAA by high-performance liquid chromatography (HPLC) complements other structural analysis techniques, such as peptide sequencing, and remains indispensable for quantifying the composition and absolute contmt of proteinaceous materials.
