TRADE NEWS: Agilent Technologies Launches Ion Trap Mass Spectrometer with Powerful New Tool for Study of Proteins.ORLANDO, Fla. -- Agilent Technologies Inc. (NYSE NYSE See: New York Stock Exchange :A) today announced the availability of the Agilent 6340 Ion Trap Liquid Chromatograph/Mass Spectrometer (LC/MS LC/MS Liquid Chromatography/Mass Spectrometry ), which allows scientists to study proteins in a manner that was previously achievable only on a million-dollar floor-standing instrument that requires a dedicated operator. The 6340, a new instrument in Agilent's 6000 Series portfolio of LC/MS systems, fits on a bench top and is equipped with an electron transfer dissociation Electron transfer dissociation (ETD) is a method to fragment ions in a mass spectrometer.[1][2] Similar to electron capture dissociation, ETD induces fragmentation of cations (e.g. peptides or proteins) by transferring electrons to them. (ETD ETD abbr. estimated time of departure Noun 1.

"The 6340 Ion Trap MS makes the fragmentation power of ETD -- formerly attainable only with Fourier-transform MS -- affordable for the average laboratory and accessible to all scientists," said Linda Lopez, product manager. "Our complete solution, which includes innovative separation technologies, the 6340 and data processing software designed expressly for ETD data, will bring unsurpassed performance, reliability and productivity to proteomics research." Proteins regulate most biological processes, and their activity is often controlled by the attachment of molecules such as phosphate groups, also known as post-translational modifications. Scientists use various approaches to identify and characterize proteins -- and chemical modifications -- that may be involved in normal biological functions or diseases such as cancer. Although ion trap mass spectrometers are a popular choice for protein studies, analysis of post-translational modifications can be challenging because standard ion fragmentation methods often cause labile labile /la·bile/ (la´bil) 1. gliding; moving from point to point over the surface; unstable; fluctuating. 2. chemically unstable. la·bile adj. 1. phosphates, glycans and other chemical modifications to dissociate dis·so·ci·ate v. dis·so·ci·at·ed, dis·so·ci·at·ing, dis·so·ci·ates v.tr. 1. To remove from association; separate: from peptides. This makes it difficult to determine the attachment point of these modifications and affords minimal peptide sequence information. Agilent's new ETD provides a "softer" mode of fragmentation that preserves these labile modifications. When operated in ETD mode, the 6340 Ion Trap provides extensive and easy-to-interpret amino acid amino acid (əmē`nō), any one of a class of simple organic compounds containing carbon, hydrogen, oxygen, nitrogen, and in certain cases sulfur. These compounds are the building blocks of proteins. sequence information in the form of complementary c- and z-series ions. Other features that make the 6340 an ideal tool for the study of post-translational modifications include the ability to alternate between ETD and collision induced dissociation (CID Cid or Cid Campeador (sĭd, Span. thēth kämpāäthōr`) [Span.,=lord conqueror], d. 1099, Spanish soldier and national hero, whose real name was Rodrigo (or Ruy) Díaz de Vivar. ) modes of fragmentation from scan to scan, which helps to pinpoint the precise identity and location of a chemical modification. In addition, neutral-loss triggered auto-MS(3) and pseudo-MS(n) modes can be used to target specific families of modifications. Unlike FT-MS devices, the 6340 supports rapid nano-scale chromatography, which facilitates "shot-gun" proteomics studies involving the analysis of all the proteins extracted from whole cell lysates (contents released during the decomposition of a cell). When used in concert with Agilent's revolutionary HPLC-Chip, the 6340 will enhance researchers' ability to identify and characterize protein modifications in extremely complex samples. The Agilent Spectrum Mill for MassHunter Workstation completes the full solution for post-translational modification studies. Other new features and advances of the 6340 include: --a high-speed data acquisition system that provides unsurpassed scan collection and transfer rates; --ETD reagent anion anion (ăn`ī'ən), atom or group of atoms carrying a negative charge. The charge results because there are more electrons than protons in the anion. monitoring; --selective or automatic charge state data collection; and --reproducible ETD spectra. Agilent offers an entire line of ion traps (6310, 6320 and 6330) to accommodate a wide range of budget and performance requirements.
