Characterization of polyphosphates by electrospray mass spectrometry
Electrospray ionization mass spectrometry (ESI-MS) was applied for the characterization of inorganic polyphosphates [orthophosphate, pyrophosphate, tripolyphosphate, trimetaphosphate, and tetrapolyphosphatel. The high selectivity of ESI-MS allows the detection of different polyphosphate species without preseparation by ion chromatography or capillary electrophoresis. Furthermore, ESI-MS does no...
متن کاملIsoelectric 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...
متن کاملProbing the oligomeric structure of an enzyme by electrospray ionization time-of-flight mass spectrometry.
Electrospray ionization time-of-flight (ESI-TOF) mass spectrometry was used to study the quaternary structure of 4-oxalocrotonate tautomerase (EC 5.3.2; 4OT), and four analogues prepared by total chemical synthesis. Wild-type 4OT is a hexamer of 62 amino acid subunits and contains no cysteine residues. The analogues were: (desPro1)4OT, a truncated construct in which Pro1 was deleted; (Cpc1)4OT ...
متن کاملVisualizing mass transport in desorption electrospray ionization using time-of-flight secondary ion mass spectrometry.
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to determine the effect of ambient probe incidence angle on the amount and direction of analyte molecules transported from the sample surface for desorption electrospray ionization (DESI). Incidence angle was critical to both the lateral dispersion and vertical take-off angles of analyte molecules desorbed from the surface; as t...
متن کاملCombined Ion Mobility/Time-of-Flight Mass Spectrometry Study of Electrospray-Generated Ions.
A commercially available ion mobility spectrometer was interfaced to a custom-built linear time-of-flight (TOF) mass spectrometer for the purpose of examining electrospray-generated plumes. Ionic species that were separated in the ion mobility spectrometer could be selectively determined with the TOF mass spectrometer. Tetraalkylammonium salts, a peptide, and proteins were examined. Their ion m...
