An ion trap storage/time‐of‐flight mass spectrometer
(The American Institute of Physics, 1992-10)
An ion trap/time‐of‐flight (TOF) mass spectrometer combination has been developed in order to combine the storage capabilities of an ion trap with the speed and resolution of a time‐of‐flight device. The ion trap is an rf ...
Proteomic profiling identifies breast tumor metastasis-associated factors in an isogenic model
(WILEY-VCH Verlag, 2007-01)
A combination of LC and MS was applied to an isogenic breast tumor metastasis model to identify proteins associated with a cellular phenotype. Chromatofocusing followed by nonporous-RP-HPLC/ESI-TOF MS was applied to cell ...
Detection of Oligonucleotides by External Injection into an Ion Trap Storage/Reflectron Time-of-flight Device
(John Wiley & Sons, Ltd., 1997-08-30)
The detection of oligonucleotides has been studied using external injection of matrix-assisted laser desorption/ionization (MALDI) produced ions into a quadrupole ion trap storage device. The ions stored in the trap are ...
Direct chemical analysis of UV laser ablation products of organic polymers by using selective ion monitoring mode in gas chromatography/mass spectrometry
(Elsevier, 1994-02)
Trace quantitites of laser ablated organic polymers were analyzed by using commercial capillary column gas chromatography / mass spectrometry; the instrument was modified so that the laser ablation products could be ...
Development and characterization of a canine oral mucosa equivalent in a serum-free environment
(Wiley Subscription Services, Inc., A Wiley Company, 2004-10-01)
The objectives of this study were to develop a serum-free system for culturing canine oral keratinocytes, the construction and characterization of a canine ex vivo produced oral mucosa equivalent (EVPOME), and transduction ...
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer
(Elsevier, 1994-02-24)
The design and performance of an ion trap storage--reflectron time-of-flight mass spectrometer (IT--RETOF MS) combination have been explored for detection of ions generated from both internal and external ionization sources. ...
The design of an atmospheric pressure ionization/time‐of‐flight mass spectrometer using a beam deflection method
(The American Institute of Physics, 1992-01)
A novel time‐of‐flight (TOF) mass spectrometer configuration has been designed which can be interfaced to a continuous ion beam source produced by atmospheric pressure ionization. The TOF device uses a beam deflection ...
Rapid identification and screening of proteins from whole cell lysates of human erythroleukemia cells in the liquid phase, using non-porous reversed phase high-performance liquid chromatography separations of proteins followed by multi-assisted laser desorption/ionization mass spectrometry analysis and sequence database searching
(John Wiley & Sons, Ltd., 1998-12-30)
Non-porous reversed phase (NPRP) high-performance liquid chromatography (HPLC) has been used as a rapid method to separate proteins from whole cell lysates of human erythroleukemia (HEL) cells. Using phosphate-buffered ...
Stability of the contractile assembly and Ca 2+ - activated tension in adenovirus infected adult cardiac myocytes
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-04)
Adenovirus-mediated gene transfer into adult cardiac myocytes in primary culture is a potentially useful method to study the structure and function of the contractile apparatus. However, the consequences of adenovirus ...
