Capillary isoelectric focusing coupled offline to matrix assisted laser desorption/ionization mass spectrometry.
This work presents several critical details for making cIEF-MALDI-MS a robust technique which will allow for more routine application and aid in automation. This includes emphasis on the hardware necessary for syringe pump mobilization and proper protocol for preventing disruption from gas bubbles. Following these guidelines, excellent elution time reproducibility is demonstrated for six pI mar...

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 کاملCapillary isoelectric focusing-mass spectrometry for shotgun approach in proteomics.
We report on capillary isoelectric focusing-mass spectrometry (CIEF-MS) of complex peptide mixtures in the absence of carrier ampholytes. Furthermore, the use of low concentrations of carrier ampholytes as mere spacers is investigated. Carrier ampholytes are complex mixtures of amphoteric compounds with high buffering capacity. Since all peptides are amphoteric compounds by themselves, the use ...

متن کاملIontophoretic fraction collection for coupling capillary zone electrophoresis with matrix-assisted laser desorption/ionization mass spectrometry.
An automated fraction collection interface has been developed for coupling capillary electrophoresis (CE) with matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS). This fraction collection approach is based on electromigration and diffusion and does not rely on the presence of a liquid junction, sheath-liquid, electro-osmotic flow, or a superimposed hydrodynamic flow. Neutr...
