  1. 1. Improved mass accuracy in MALDI-TOF-MS analysis

    Author : Martin Kempka; Johan Roeraade; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; MALDI; mass spectrometry; mass accuracy; peak picking; ion formation; proteins; peptides; chip; sample handling; sensitivity.; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. READ MORE

  2. 2. Improved Neuropeptide Identification : Bioinformatics and Mass Spectrometry

    Author : Maria Fälth Savitski; Per Andrén; David Fenyö; Per Svenningsson; Ronald Beavis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; neuropepides; database; peptide identification; peptide fragmentation; mass spectrometry; tandem mass spectromerty; Bioinformatics; Bioinformatik;

    Abstract : Bioinformatic methods were developed for improved identification of endogenous peptides using mass spectrometry. As a framework for these methods, a database for endogenous peptides, SwePep, was created. It was designed for storing information about endogenous peptides including tandem mass spectra. READ MORE
