Higher-energy collisional dissociation hcd
Web21 de nov. de 2016 · Analysis of intact glycopeptides by mass spectrometry is essential to determining the microheterogeneity of protein glycosylation. Higher-energy collisional dissociation (HCD) fragmentation of glycopeptides generates mono- or disaccharide ions called oxonium ions that carry information about the structure of the fragmented glycans. WebObtained results are compared with those found previously by low-energy CID. The use of this HCD technique is relatively straightforward, although its implementation does require …

Higher-energy C-trap dissociation (HCD) is a CID technique specific to the orbitrap mass spectrometer in which fragmentation takes place external to the trap. HCD was formerly known as higher-energy C-trap dissociation. In HCD, the ions pass through the C-trap and into the HCD cell, an added multipole … Ver mais Collision-induced dissociation (CID), also known as collisionally activated dissociation (CAD), is a mass spectrometry technique to induce fragmentation of selected ions in the gas phase. The selected ions … Ver mais In a triple quadrupole mass spectrometer there are three quadrupoles. The first quadrupole termed "Q1" can act as a mass filter and transmits a selected ion and accelerates it towards "Q2" which is termed a collision cell. The pressure in Q2 is higher and the … Ver mais Homolytic fragmentation is bond dissociation where each of the fragments retains one of the originally-bonded electrons. Ver mais Low-energy CID is typically carried out with ion kinetic energies less than approximately 1 kiloelectron volt (1 keV). Low-energy CID is highly efficient in fragmenting the selected precursor ions, but the type of fragment ions observed in low-energy CID is … Ver mais Ions trapped in the ICR cell can be excited by applying pulsed electric fields at their resonant frequency to increase their kinetic energy. The duration and amplitude of the pulse determines the ion kinetic energy. Because a collision gas present at low pressure … Ver mais • Electron-capture dissociation (ECD) • Electron-transfer dissociation (ETD) • Infrared multiphoton dissociation (IRMPD) Ver mais WebHowever, assigning these spectra, leading to identification of the glycopeptides, is challenging. Here, we report an algorithm, named GPQuest, for site-specific identification of intact glycopeptides using higher-energy collisional dissociation (HCD) fragmentation of complex samples.
