Gas-phase diagnostics and LIF-imaging of 3-hydroxypicolinic acid MALDI-matrix plumes

Puretzky AA and Geohegan DB

Chemical Physics Letters, 286(5-6), 425-432 (1998)

Matrix-assisted laser desorption/ionization mass spectrometry of immobilized duplex DNA probes.

K Tang et al.

Nucleic acids research, 23(16), 3126-3131 (1995-08-25)

Matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometry was used to analyze short DNA duplex probes with one strand immobilized on solid supports (straptavidin-coated magnetic beads or controlled pore glass beads). Only the non-immobilized strand could be detected. Partial denaturation

Utility of non-covalent complexes in the matrix-assisted laser desorption ionization mass spectrometry of heparin-derived oligosaccharides.

P Juhasz et al.

Carbohydrate research, 270(2), 131-147 (1995-04-30)

Molecular weights of heparin-derived oligosaccharides ranging from disaccharides to hexadecasaccharides have been determined by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. While these compounds ionize poorly or not at all when used as such, a strong signal can be obtained

Analysis of 1-aminopyrene-3,6,8-trisulfonate-derivatized oligosaccharides by capillary electrophoresis with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

H Suzuki et al.

Analytical chemistry, 69(22), 4554-4559 (1998-01-07)

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), has been used for structure characterization of 1-aminopyrene-3,6,8-trisulfonate (APTS)-derivatized oligosaccharides previously separated by capillary electrophoresis (CE). The resolved components were first isolated by employing an automated high-resolution fraction collector. Using on-probe sample

Isolation and characterization of quinoline-degrading bacteria from subsurface sediments.
