  1. 1. Chemical labelling methods for gel free based proteomics

    Author : Åsa Wåhlander; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; 2D-HPLC; isotopes; labelling; proteomics; mass spectrometry;

    Abstract : In this thesis different aspects of gel free procedures for mass spectrometry based proteome analysis are addressed, with emphasis on labelling techniques. It is based on three original articles where the effects imposed onto peptides upon modification are investigated, and the development of a new type of labelling strategy is described. READ MORE

  2. 2. Synthesis of 11C-labelled Alkyl Iodides : Using Non-thermal Plasma and Palladium-mediated Carbonylation Methods

    Author : Jonas Eriksson; Bengt Långström; Philip H. Elsinga; Uppsala universitet; []
    Keywords : Organic chemistry; isotopic labelling; carbon-11; alkyl iodides; acrylamides; specific radioactivity; carbonylation; carbon monoxide; non-thermal plasma; PET; Organisk kemi;

    Abstract : Compounds labelled with 11C (β+, t1/2 = 20.4 min) are used in positron emission tomography (PET), which is a quantitative non-invasive molecular imaging technique. It utilizes computerized reconstruction methods to produce time-resolved images of the radioactivity distribution in living subjects. READ MORE

  3. 3. Structural Studies of O-antigen polysaccharides, Synthesis of 13C-labelled Oligosaccharides and Conformational Analysis thereof, using NMR Spectroscopy

    Author : Ulrika Olsson; Göran Widmalm; Corine Sandström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; conformation; Escherichia coli; lipopolysaccharide; O-antigen; carbohydrates; structure; isotopic labelling; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : In order to understand biological processes, to treat and diagnose diseases, find appropriate vaccines and to prevent the outbreak of epidemics, it is essential to obtain more knowledge about carbohydrate structures. This thesis deals with structure and conformation of carbohydrates, analysed by NMR spectroscopy and MD simulations. READ MORE

  4. 4. Design and Synthesis of 11C-Labelled Compound Libraries for the Molecular Imaging of EGFr, VEGFr-2, AT1 and AT2 Receptors : Transition-Metal Mediated Carbonylations Using [11C]Carbon Monoxide
