2. 1. Staphylococcal surface display in directed evolution

   Author : Nina Kronqvist; Stefan Ståhl; Mats A. A. Persson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; combinatorial library; directed evoluation; Gram-positive bacteria. protein engineering; Bioengineering; Bioteknik;

   Abstract : Engineered affinity proteins have together with naturally derived antibodies becomeindispensable tools in many areas of life-science and with the increasing number ofapplications, the need for high-throughput methods for generation of such different affinityproteins is evident. Today, combinatorial protein engineering is the most successful strategy toisolate novel non-immunoglobulin affinity proteins. READ MORE

4. 2. Molecular principles of protein stability and protein-protein interactions

   Author : Christofer Lendel; Per-Åke Nygren; Christopher M. Dobson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; binding thermodynamics; induced fit; molten globule; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; protein structure.; Structural biochemistry; Strukturbiokemi;

   Abstract : Proteins with highly specific binding properties constitute the basis for many important applications in biotechnology and medicine. Immunoglobulins have so far been the obvious choice but recent advances in protein engineering have provided several novel constructs that indeed challenge antibodies. READ MORE

5. 3. Structure determination and thermodynamic stabilization of an engineered protein-protein complex

   Author : Elisabet Wahlberg; Per-Åke Nygren; Bengt-Harald Jonsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; protein structure; coupled folding; NMR spectroscopy; protein stability; protein-protein interactions; binding thermodynamics; isothermal titration calorimetry; protein engineering; Structural biochemistry; Strukturbiokemi;

   Abstract : The interaction between two 6 kDa proteins has been investigated. The studied complex of micromolar affinity (Kd) consists of the Z domain derived from staphylococcal protein A and the related protein ZSPA-1, belonging to a group of binding proteins denoted affibody molecules generated via combinatorial engineering of the Z domain.

6. 4. Protein engineering to explore and improve affinity ligands

   Author : Martin Linhult; KTH; []
   Keywords : binding; affinity; human serum albumin HSA ; albumin-binding domain ABD ; affinity chromatography; deamidation; protein A; stabilization; Z-domain; capacity; protein G; cleaning-in-place CIP ; protein engineering; C2 receptor;

   Abstract : In order to produce predictable and robust systems forprotein purification and detection, well characterized, small,folded domains descending from bacterial receptors have beenused. These bacterial receptors, staphylococcal protein A (SPA)and streptococcal protein G (SPG), possess high affinity to IgGand / or HSA. READ MORE

7. 5. Recombinant subunit vaccines : protein immunogens

   Author : Sissela Liljeqvist; KTH; []
   Keywords : ;

   Abstract : 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. READ MORE
