  1. 1. Evolutionary and functional studies of protein H: a surface molecule of Streptococcus pyogenes

    Author : Inga-Maria Frick; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intracellular transportation; adhesion; aggregation; FNIII domain; albumin-binding; M-like protein; convergent evolution; protein G; Streptococcus pyogenes; IgG-binding; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Several bacterial species express surface proteins with affinity for the Fc part of human IgG. This thesis describes evolutionary and functional studies of protein H, an IgGFc-binding surface protein of the human pathogen Streptococcus pyogenes. READ MORE

  2. 2. Engineering of small IgG binding domains for antibody labelling and purification

    Author : Sara Kanje; Sophia Hober; Cecília Roque; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Antibody; labelling; purification; Protein G; Protein A; protein engineering; protein design; combinatorial selection; Biotechnology; Bioteknologi;

    Abstract : In protein engineering, rational design and selection from combinatorial libraries are methods used to develop proteins with new or improved features. A very important protein for the biological sciences is the antibody that is used as a detecting agent in numerous laboratory assays. READ MORE

  3. 3. Site-specific labeling of affinity molecules for in vitro and in vivo studies

    Author : Anna Perols; Amelie Eriksson Karlström; Christian Hackenberger; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Affibody molecules; molecular imaging; site-specific labeling; solid phase peptide synthesis; IgG-binding domains; photoconjugation.; Bioteknologi; Biotechnology;

    Abstract : The thesis is focused on site-specific labeling of affinity molecules for different applications where two types of binding proteins, Affibody molecules and antibodies, have been used. For the purpose of improving the properties of Affibody molecules for in vivo imaging, novel bi-functional chelators for radiolabeling using the radionuclide 111In were evaluated. READ MORE

  4. 4. Molecular analysis of Streptococcus pyogenes and its interactions with the human host

    Author : Andreas Berge; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement activation; fibrinogen; IgG; M protein; C5a peptidase; streptococcal cysteine proteinase; streptokinase; t-PA; Streptococcus pyogenes; plasminogen; C1q; insertional sequence.; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Streptococcus pyogenes causes infections only in humans, from trivial tonsillitis to life-threatening conditions. One of its most important virulence factors is the M-like protein family conferring resistance to phagocytosis to the bacterium. The M-like proteins are surface exposed rod-like molecules attached to the cell wall. Each strain of S. READ MORE

  5. 5. Design, selection and production of recombinant proteins for prevention of infectious diseases

    Author : Marianne Hansson; KTH; []
    Keywords : ;

    Abstract : The development of subunit vaccines is presently one of themain strategies for the generation of new vaccines againstinfectious diseases. The use of recombinant DNA techniques hasfacilitated the develoment of new strategies for constructionand production of subunit vaccines. READ MORE
