Probing Disulfide Bond Structure with Top Down Mass Spectrometry

31 Aug 2014

This poster demonstrates top down mass spectrometry on a range of proteins of various sizes containing disulfide bonds. This is performed using ETD, ECD and MALDI-ISD to investigate the influence that different activation methods have on sequence coverage.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Structural BiologyProtein StructureProtein structure refers to the three-dimensional arrangement of amino acids in proteins, determining their function. Understanding protein structure is key in drug discovery, enzymology, and molecular biology.
