Journal ArticleDOI
Charting the Proteomes of Organisms with Unsequenced Genomes by MALDI-Quadrupole Time-of-Flight Mass Spectrometry and BLAST Homology Searching
Andrej Shevchenko,Shamil R. Sunyaev,Alexandre V. Loboda,Peer Bork,Werner Ens,Kenneth G. Standing +5 more
TL;DR: A "MS BLAST" homology searching protocol was developed to overcome specific limitations imposed by mass spectrometric data, such as the limited accuracy of de novo sequence predictions.
Journal ArticleDOI
A tandem quadrupole/time-of-flight mass spectrometer with a matrix-assisted laser desorption/ionization source: design and performance
TL;DR: A matrix-assisted laser desorption/ionization source has been coupled to a tandem quadrupole/time-of-flight (QqTOF) mass spectrometer by means of a collisional damping interface and Ion production at pressures near 1 Torr is found to give reduced metastable fragmentation, particularly for higher mass molecular ions.
Journal ArticleDOI
Orthogonal injection of matrix-assisted laser desorption/ionization ions into a time-of-flight spectrometer through a collisional damping interface
Andrew N. Krutchinsky,Alexandre V. Loboda,Victor Spicer,Ragnar G. Dworschak,Werner Ens,Kenneth G. Standing +5 more
TL;DR: In this paper, a matrix-assisted laser desorption/ionization (MALDI) target is produced by irradiation with a nitrogen laser pulsed at 20 kHz. But the performance of the system is independent of the source conditions.
Patent
Spectrometer provided with pulsed ion source and transmission device to damp ion motion and method of use
TL;DR: In this article, a method and apparatus for providing an ion transmission device or interface between an ion source and a spectrometer is described, which can have a number of effects, including: substantially spreading out the generated ions along an ion axis to generate a quasi-continuous beam; reducing the energy spread of ions emitted from the source; and at least partially suppressing unwanted fragmentation of analyte ions.
Journal ArticleDOI
Characterization of a novel potyvirus isolated from Maize in Israel
Dallas L. Seifers,R. Salomon,V. Marie-Jeanne,B. Alliot,P. Signoret,S. Haber,Alexandre V. Loboda,Werner Ens,Yi-Min She,Kenneth G. Standing +9 more
TL;DR: The nucleic acid and amino acid sequences of ZeMV clearly showed that it is not a strain of JGMV, MDV, SCMV, or SrMV.
