  1. 6. Affibody molecules for proteomic and therapeutic applications

    Författare :Caroline Grönwall; Stefan Ståhl; Lena Jendeberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; protein engineering; phage display; amyloid beta peptide; transferrin; CD25; IL-2 receptor; proteomics; Bioengineering; Bioteknik;

    Sammanfattning : This thesis describes generation and characterization of Affibody molecules with future applications in proteomics research, protein structure determinations, therapeutic treatment of disease and medical imaging for in vivo diagnostics. Affibody molecules are engineered affinity proteins developed by combinatorial protein engineering from the 58-residue protein A-derived Z domain scaffold. LÄS MER

  2. 7. Affibody Molecules Targeting VEGFR2 - Two Turns Off and Four Turns On

    Författare :Rezan Güler; John Löfblom; Stefan Ståhl; Dario Neri; KTH; []
    Nyckelord :Protein engineering; affibody molecules; VEGFR2; angiogenesis; Bioteknologi; Biotechnology;

    Sammanfattning : The notion of employing proteins as drugs traces back several decades. As recombinant DNA technology emerged, it became a powerful tool for the tailoring of protein traits via genetic approaches - so-called protein engineering. LÄS MER

  3. 8. Development of new affinity proteins for neurodegenerative disorders

    Författare :Linnea C. Hjelm; John Löfblom; Stefan Ståhl; Hanna Lindberg; Ylva Ivarsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein engineering; sequestrins; amyloid beta; alpha-synuclein; phage display; affibodies; blood–brain barrier; Transferrin receptor; receptor-mediated transcytosis; recombinant spider silk; Biotechnology; Bioteknologi;

    Sammanfattning : Neurodegenerative disorders include a full spectrum of diagnoses, including dementias and other neuronal diseases, characterised by degradation of neurons in the brain occurring along with disease progression. Amongst the dementias, the most prevalent are Alzheimer’s (AD) and Parkinson’s disease (PD) that affect millions of people worldwide. LÄS MER

  4. 9. Development of molecular recognition by rational and combinatorial engineering

    Författare :Andreas Jonsson; Stefan Ståhl; Mats Persson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Affibody molecule; albumin binding domain; protein engineering; phage display; amyloid beta peptide; TNF; HSA; Molecular biology; Molekylärbiologi;

    Sammanfattning : Combinatorial protein engineering, taking advantage of large libraries of protein variants and powerful selection technology, is a useful strategy for developing affinity proteins for applications in biotechnology and medicine. In this thesis, two small affinity proteins have been subjected to combinatorial protein engineering to improve or redirect the binding. LÄS MER

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

    Författare :George Kostallas; Stefan Ståhl; Patrik Samuelson; Matthew DeLisa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; proteases; flow cytometry; GFP; CAT; protein engineering; ssrA; ClpXP; tobacco etch virus; TEV; site-specific; high-throughput; selection; proteolysis; libraries; Bioengineering; Bioteknik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : 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. LÄS MER
