1. 11. Rational and combinatorial genetic engineering approaches for improved recombinant protein production and purification

   Författare :Nina Bandmann; Per-Åke Nygren; Helena Berglund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aqueous two-phase system; combinatorial library; expression vector; flow cytometry; fusion tag; partitioning; peptide library; phage display; recombinant proteins; ribosomal binding site; translation initiation; Bioengineering; Bioteknik;

   Sammanfattning : The bacterium Escherichia coli (E. coli) is in many situations an ideal host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve sufficiently high product quantities. LÄS MER

3. 12. Metal Binding Tags - Characterisation, Use in Bioseparation and Applications of Green Fluorescent Fusion Proteins

   Författare :Florent Bernaudat; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; enzymology; E. coli; Immobilised metal ion affinity chromatography; Affinity tags; Green fluorescent protein; Surface plasmon resonance; Genetic engineering; Screening; Proteins; Immunoassay; Biotechnology; Bioteknik;

   Sammanfattning : Most of the recombinant proteins produced nowadays are fused to affinity tags, in order to facilitate their purification through affinity chromato-graphy. Out the different tags available, poly-histidine tags are among the most commonly used and can help purification through immobilised metal ion affinity chromatography (IMAC). LÄS MER

4. 13. Growth rate control of periplasmic product retention in Escherichia coli

   Författare :Emma Bäcklund; Gen Larsson; Stefan Schmidt; Amelie Eriksson Karlström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Escherichia coli; fed-batch; outer membrane proteins; recombinant proteins; specific growth rate; periplasmic retention; phosphotransferase system; high cell density cultivation; acetate formation; Bioengineering; Bioteknik;

   Sammanfattning : The recombinant product is secreted to the periplasm in many processes where E. coli is used as host. One drawback with secretion is the undesired leakage of the periplasmic products to the medium. The aim of this work was to find strategies to influence the periplasmic retention of recombinant products. LÄS MER

5. 14. Engineering yeast for improved recombinant protein production

   Författare :Yanyan Wang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; point mutation; genome-scale modeling; recombinant protein; omics analysis; CRISPR Cas9; protein secretion; Saccharomyces cerevisiae;

   Sammanfattning : Recombinant proteins are broadly used from basic research to therapeutic development and include industrial enzymes and pharmaceutical proteins. The increasing demand for improved production and enhanced quality of recombinant proteins requires robust biotech-based strategies to overcome the limitations of protein extraction from natural sources.
