  1. 16. Programmed Cell Death in Xylem Development

    Författare :Laetitia Charleen Courtois-Moreau; Hannele Tuominen; Stefan Jansson; Christina Dixelius; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCD Programmed Cell Death ; Xylem; Apoptosis; Autophagy; Secondary Cell Walls; Microscopy; Microarrays; Comet Assay; TUNEL Assay; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Concerns about climate changes and scarcity of fossil fuels are rising. Hence wood is becoming an attractive source of renewable energy and raw material and these new dimensions have prompted increasing interest in wood formation in trees, in both the scientific community and wider public.

  3. 17. HIV-1 reverse transcriptase activity assays based on monoclonal antibodies to native enzyme : Applications on studies of antiviral substances and immunological variation of reverse transcriptase

    Författare :Ann-Sofie Rytting; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; HIV-1; reverse transcriptase; monoclonal antibody; activity assay; subtype; RT inhibitor; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Sammanfattning : Specific detection of HIV-1 reverse transcriptase (RT) activity in crude materials was enhanced using a capture assay for immunopurification and subsequent activity assay. The purification step was achieved by anti-HIV-1 RT monoclonal antibodies (Mabs) immobilized onto a solid carrier. LÄS MER

  4. 18. Development and Application of Proximity Assays for Proteome Analysis in Medicine

    Författare :Felipe Marques Souza de Oliveira; Masood Kamali-Moghaddam; Ulf Landegren; Mats Gullberg; Janne Lehtiö; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solid-phase proximity ligation assay; post-translational modifications; glycosylation; phosphorylation; Enzyme-linked immunosorbent assay; immunoassay and rolling circle amplification; Proximity Extension Assay; inflammation protein biomarkers; autoantibodies; autoimmune disease;

    Sammanfattning : Along with proteins, a myriad of different molecular biomarkers, such as post-translational modifications and autoantibodies, could be used in an attempt to improve disease detection and progression. In this thesis, I build on several iterations of the proximity ligation assay to develop and apply new adaptable methods to facilitate detection of proteins, autoantibodies and post-translational modifications.

  5. 19. Thiopurine S-methyltransferase - characterization of variants and ligand binding

    Författare :Annica Blissing; Lars-Göran Mårtensson; Tomas Nyman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Thiopurine S-methyltransferase TPMT ; protein stability; enzyme kinetics; ligand binding; isothermal titration calorimetry ITC ; 8-anilinonaphthalene-1-sulfonic acid ANS ;

    Sammanfattning : Thiopurine S-methyltransferase (TPMT) belongs to the Class I S-adenosylmethionine-dependent methyltransferase (SAM-MT) super family of structurally related proteins. Common to the members of this large protein family is the catalysis of methylation reactions using S-adenosylmethionine (SAM) as a methyl group donor, although SAM-MTs act on a wide range of different substrates and carry out numerous biologically important functions.

  7. 20. Development of sensitive cellular assay systems and their application to the identification of "orphan" seven-transmembrane receptors

    Författare :Knut Kotarsky; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemi; Metabolism; Biochemistry; metabolism; leukotrieneB4; thiazolidinedione; 9-HODE; fatty acid; luciferase; GFP; reporter gene; preclinical assay; receptor; GPCR;

    Sammanfattning : Seven-transmembrane, G-protein coupled receptors play a central role in physiology since they facilitate cell communication in multicellular organisms by recognition of a broad range of ligands. They also represent important drug targets. LÄS MER
