matrix-assisted laser desorption/ionization time of flight mass spectrometry: a new guide to infectious disease

Identification and Classification of Rhizobia by Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight Mass Spectrometry

Mass spectrometry (MS) has been widely used for specific, sensitive and rapid analysis of proteins and has shown a high potential for bacterial identification and characterization. Type strains of four species of rhizobia and Escherichia coli DH5α were employed as reference bacteria to optimize various parameters for identification and classification of species of rhizobia by matrix-assisted la...

DNA sequencing by delayed extraction-matrix-assisted laser desorption/ionization time of flight mass spectrometry.

Matrix-assisted laser desorption/ionization (MALDI) time of flight mass spectrometry was used to detect and order DNA fragments generated by Sanger dideoxy cycle sequencing. This was accomplished by improving the sensitivity and resolution of the MALDI method using a delayed ion extraction technique (DE-MALDI). The cycle sequencing chemistry was optimized to produce as much as 100 fmol of each ...

Identification of urinary oligosaccharides by matrix-assisted laser desorption ionization time-of-flight mass spectrometry.

A new method of urinary oligosaccharides identification by matrix-assisted laser desorption time-of-flight mass spectrometry is presented. The method involves three steps: coupling of the urinary oligosaccharides with 8-aminonaphthalene-1,3,6-trisulfonic acid; fast purification over a porous graphite carbon extraction column; and mass spectrometric analysis. Identification of urinary oligosacch...

Isoelectric Focusing, Matrix-assisted Laser Desorption/ionization Time-of- Flight Mass Spectrometry, Electrospray Ionization Mass Spectrometry

LEVEL: INTERMEDIATE D iscovery, development, and commercialization of novel biologics frequently involve collaboration between two or more companies. In the context of these business relationships, transfer of technology from one institution to another is a crucial step that needs to be executed f lawlessly and rapidly. Follow-up activities usually include the development of productive, reliabl...
