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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

    Abstract : I denna avhandling presenteras arbete utfört med enzymet humant karboanhydras II (HCAII). Enzymer är en typ av proteiner som accelererar (katalyserar) kemiska reaktioner, vilket är nödvändigt för allt levande. Den naturliga funktionen för HCAII är att katalysera omvandlingen av gasen koldioxid till vätekarbonat, som är löslig i vätska. READ MORE

  5. 5. Intracellular systems for characterization and engineering of proteases and their substrates

    Abstract : Over the years, the view on proteases as relatively non-specific protein degradation enzymes, mainly involved in food digestion and intracellular protein turnover, has shifted and they are now recognized as key regulators of many biological processes that determine the fate of a cell. Besides their biological role, proteases have emerged as important tools in various biotechnical, industrial and medical applications. READ MORE
