1. 11. Recombinant subunit vaccines : protein immunogens

   Författare :Sissela Liljeqvist; KTH; []
   Nyckelord :;

   Sammanfattning : Recombinant techniques provide valuable tools for thedevelopment of modern subunit vaccines. In this thesisdifferent systems for production of recombinant subunitvaccines are presented. The strategies investigated includeprotein immunogens, live bacterial vectors and nucleicacids. LÄS MER

3. 12. The birth and growth of the protein folding nucleus : Studies of protein folding focused on critical contacts, topology and ionic interactions

   Författare :Linda Hedberg; Mikael Oliveberg; Christopher Johnson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; chevron plot; transition-state movements; Hammond behaviour; topology; electrostatic interactions; pH dependence; mass-action; protein engineering; pKa; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Proteins are among the most complex molecules in the cell and they play a major role in life itself. The complexity is not restricted to just structure and function, but also embraces the protein folding reaction. LÄS MER

4. 13. Immunoglobulin-binding bacterial surface proteins; biomedical tools and virulence factors

   Författare :Britt-Marie Kihlberg; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phagocytosis; M-like protein; M protein; Protein L; Protein G; Ig-binding; Streptococcus pyogenes; Fc Receptors; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Cysteine proteinase; Streptolysin;

   Sammanfattning : Many bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. LÄS MER

5. 14. Fouling and cleaning of solid surfaces. The influence of surface characteristics and operating conditions

   Författare :Camilla Karlsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; ellipsometry; sodium hydroxide; anionic surfactant; betalactoglobulin; protein; stainless steel; hydrophilic surface; hydrophobic surface; cleaning; adsorption; fouling; Livsmedelsteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : The severe fouling common in food processing puts high demands on equipment cleaning. Adsorption of the protein betalactoglobulin to solid surfaces and its subsequent removal were followed using in situ ellipsometry. Most experiments were done in a stirred cuvette. Additionally, a flow cell was designed, which was employed in some work. LÄS MER

7. 15. Water and protein solutions studied by field-dependent magnetic relaxation

   Författare :Kristofer Modig; Biofysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relaxation; protein solvation; protein dynamics; protein denaturation; oxytocin; magnetic relaxation dispersion; nuclear magnetic resonance; lipid-binding protein; hydration; beta-lactoglobulin; BPTI; shielding anisotropy; water; Molecular biophysics; Molekylär biofysik;

   Sammanfattning : In the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. LÄS MER
