1. 1. Protein engineering to explore and improve affinity ligands

   Författare :Martin Linhult; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

   Författare :Gösta Lilius; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

   Sammanfattning : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

4. 3. Affinity Two-Phase Partitioning of Liposomes and Membranes

   Författare :Irene Barinaga-Rementeria Ramírez; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturised two-phase system; levitated drop; biotin; avidin; antibody; immunoaffinity; purification; rat lung; rat liver; caveolae; membrane; Affinity two-phase partitioning; liposome; Metabolism; Biochemistry; Biokemi; metabolism;

   Sammanfattning : Affinity two-phase partitioning based on an immunoaffinity sandwich approach for the rapid and selective purification of membranes is presented in this thesis. The method was developed by studying different parameters governing the affinity partitioning of model membranes. To this end, biotinylated liposomes were used. LÄS MER

5. 4. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

   Författare :Malin Mejàre; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

   Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

7. 5. An albumin-binding domain as a scaffold for bispecific affinity proteins

   Författare :Johan Nilvebrant; Sophia Hober; Andrew Bradbury; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; albumin-binding domain; bispecific; albumin; affinity protein; phage display; staphylococcal display; orthogonal affinity purification; TNF-alpha; ErbB2; ErbB3; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

   Sammanfattning : Protein engineering and in vitro selection systems are powerful methods to generate binding proteins. In nature, antibodies are the primary affinity proteins and their usefulness has led to a widespread use both in basic and applied research. LÄS MER
