  1. 1. Combinatorial Methodology. Screening for affinity specific ligands to biological and artificial receptors

    Författare :Margareta Krook; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptide library; combinatorial; screening; phage display; affinity; DNA-interaction; chymotrypsin; peptide inhibitor; antibody; IgG; Fc; molecular imprinting; steroid; receptor; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik;

    Sammanfattning : Combinatorial screening methodology has been employed to select new affinity specific ligands to bilogical and artificial receptors. The screening methodology, in particular screening of combinatorial phage display peptide libraries against target molecules differing in function and shape, is focused upon. LÄS MER

  2. 2. Exploring molecular interactions between polypeptide conjugates and protein targets : Manipulating affinity by chemical modifications

    Författare :Aleksandra Balliu; Lars Baltzer; Oliver Seitz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polypeptide conjugates; protein targets; molecular recognition; affinity enhancement; conjugation;

    Sammanfattning : In this thesis molecular interactions between polypeptide conjugates and protein targets were investigated. Polypeptides were derivatized with small organic molecules, peptides and oligonucleotides. New strategies were developed with the aim to increase affinities for proteins of biological interest.

  3. 3. An albumin-binding domain as a scaffold for bispecific affinity proteins

    Författare :Johan Nilvebrant; Sophia Hober; Andrew Bradbury; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; albumin-binding domain; bispecific; albumin; affinity protein; phage display; staphylococcal display; orthogonal affinity purification; TNF-alpha; ErbB2; ErbB3; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : Protein engineering and in vitro selection systems are powerful methods to generate binding proteins. In nature, antibodies are the primary affinity proteins and their usefulness has led to a widespread use both in basic and applied research. LÄS MER

  4. 4. Engineering of Affibody molecules for Radionuclide Molecular Imaging and Intracellular Targeting

    Författare :Camilla Hofström; Torbjörn Gräslund; Serge Muyldermans; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody molecules; affinity proteins; radionuclide molecular imaging; intracellular targeting; EGFR; HER2; IGF-1R; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : Affibody molecules are small (7 kDa) affinity proteins of non-immunoglobulin origin that have been generated to specifically interact with a large number of clinically important molecular targets.In this thesis, Affibody molecules have been employed as tracers for radionuclide molecular imaging of HER2- and IGF-1R-expressing tumors, paper I-IV, and for surface knock-down of EGFR, paper V.

  5. 5. Computational prediction of receptor-ligand binding affinity in drug discovery

    Författare :John Marelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; computer-aided ligand design; molecular dynamics simulation; linear interaction energy; free energy perturbation; scoring function; dihydrofolate reductase; thrombin; serine proteases; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; molekylär bioteknik avd f jonfysik ;

    Sammanfattning : The evaluation of inhibition constants or, more generally, receptor-ligand binding affinities is a crucial part of the drug discovery process. Chemical synthesis and affinity screening is only affordable for a limited number of compounds. This makes computational methods to predict binding affinities of candidate ligands highly desirable.
