  1. 1. Analysis of noncovalent and covalent protein-ligand complexes by electrospray ionisation mass spectrometry

    Författare :Gustav Sundqvist; Harry Brumer; Per Andrén; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; noncovalent complex; droplet fission; nano-electrospray ionisation; mass spectrometry; Analytical chemistry; Analytisk kemi;

    Sammanfattning : In this thesis, the application of electrospray ionisation mass spectrometry (ESI-MS) to the analysis of intact proteins is demonstrated. In papers I and II, the use of ESI-MS for the analysis of noncovalent protein-ligand complexes were discussed. LÄS MER

  3. 2. On-line Electrochemistry Electrospray Ionisation Mass Spectrometry : Method Development and Applications

    Författare :Camilla Zettersten; Leif Nyholm; Per Sjöberg; Andries P. Bruins; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis deals with studies of on-line electrochemistry electrospray ionisation mass spectrometry (EC/ESI-MS). It is shown that the use of EC/ESI-MS demands optimal coupling characteristics. Pre-concentration and desalting, due to matrix exchange, were demonstrated for the model substance 1-hexanethiol in an EC/ESI-MS setup. LÄS MER

  5. 4. Advanced computations and mass-spectrometric techniques to unravel the dynamics and interactions of proteins

    Författare :Joana Costeira-Paulo; Erik Marklund; Lars Konermann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; mass spectrometry; dihydroorotate dehydrogenase; alpha-synuclein; protein structure; ion mobility; electrospray ionisation; collision cross section; lipids; gas-phase hydrogen deuterium exchange; collision induced unfolding; Biokemi; Biochemistry;

    Sammanfattning : Proteins are an important class of biomolecules, involved in the metabolism, regulation, structure and transport in cells. Unfortunately, many diseases are caused by protein dysfunction. When proteins perform their normal function, they may interact with each other or change their conformation. LÄS MER

  7. 5. Mass spectrometric studies of cellulose ethers

    Författare :Dane Momcilovic; Centrum för analys och syntes; []
