1. 31. Combinatorial protein engineering applied to enzyme catalysis and molecular recognition

   Författare :Malin Eklund; KTH; []
   Nyckelord :phage display; selection; enzyme; affinity domains; crystal structure; affibody; lipase; protein engineering; protein A; assembly;

   Sammanfattning : The recent development of methods for constructing andhandling large collections (libraries) of proteins, from whichvariants with desired traits can be isolated, hasrevolutionized the field of protein engineering. Key elementsof such methods are the various ways in which the genotypes(the genes) and the phenotypes (the encoded proteins) arephysically linked during the process. LÄS MER

3. 32. NMR studies on interactions between the amyloid β peptide and selected molecules

   Sammanfattning : Alzheimer’s disease is an incurable neurodegenerative disorder linked to the amyloid β (Aβ) peptide, a 38-43 residue peptide. The detailed molecular disease mechanism(s) is (are) unknown, but oligomeric Aβ structures are proposed to be involved. LÄS MER

4. 33. Staphylococcal surface display in directed evolution

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Elisabet Wahlberg; Per-Åke Nygren; Bengt-Harald Jonsson; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.

7. 35. Bioimaging for analysis of protein expression in cells and tissues using affinity reagents

   Författare :Emma Lundberg; Torbjörn Gräslund; Mathias Uhlén; Rainer Pepperkok; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Affibody; antibody; biomarker; cell line; cell microarray; colorectal cancer; confocal microscopy; HER2; immunohistochemistry; immunofluorescence; light microscopy; protein expression; protein localization; SATB2; tissue microarray; Bioengineering; Bioteknik; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : The detection and analysis of biomolecules, such as proteins, are of great interest since these molecules are fundamental for life and our health. Due to the complexity of biological processes, there is a great advantage of studying proteins in their natural context, for example by using bioimaging. LÄS MER
