  1. 1. Peptide-tagged proteins in aqueous two-phase systems

    University dissertation from Prof. Folke Tjerneld, Dept. Biochemistry, Lund University

    Author : Anna Nilsson; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; green fluorescent protein; cutinase; tryptophan; Aqueous two-phase system; peptide-tagged protein;

    Abstract : Popular Abstract in Swedish När en dressing tillreds används ofta olja, vinäger och kryddor. Även om dressingen skakas ordentligt kommer den efter ett tag att dela upp sig i två lösningar, en med olja och en med vinäger. Ett tvåfassystem har bildats där kryddorna fördelar sig mellan olje- och vinägerfasen. READ MORE

  2. 2. Recombinant protein purification using thermoseparating aqueous two-phase systems

    University dissertation from Prof. Folke Tjerneld, Dept. of Biochemistry, Lund University

    Author : Josefine Persson; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer recycling.; partitioning; apolipoprotein A-I; thermoseparation; bioseparation; Aqueous two-phase systems; polymer; Biology; Biologi;

    Abstract : The biotechnology industry has grown considerably over the past twenty years, and the revolution within the field of molecular biology has dramatically improved the possibilities of producing proteins and other important biomolecules. The product of interest will be obtained in a multi-component solution and some challenging purification work has to be performed to recover the target molecule in a pure form. READ MORE

  3. 3. Protein Surfaces Probed by Aqueous Two-phase Partitioning

    University dissertation from Department of Biochemistry, Lund University

    Author : Kristina Berggren; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; partitioning; Aqueous two-phase systems; protein surface; peptide; Biochemistry; amino acid residue; Biokemi;

    Abstract : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. READ MORE

  4. 4. Lactic acid production: extractive fermentation in aqueous two-phase systems

    University dissertation from Department of Applied Microbiology, Lund University

    Author : Jordi Planes; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel excludion chromatography; polyethylenimine; ethylene oxide propylene oxide; phase forming polymers; aqueous two-phase systems; extractive fermentation; Lactococcus; Lactobacillus; Mikrobiologi; bakteriologi; virologi; mykologi; bacteriology; virology; mycology; Microbiology;

    Abstract : There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the recovery of lactic acid.

  5. 5. Integration of Aqueous Two-Phase Systems into Recovery Processes for Biomolecules

    University dissertation from Folke Tjerneld, Department of Biochemistry, Lund University

    Author : Cecilia Kepka; Lunds universitet.; Lund University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteins; proteins; plasmid DNA; large-scale; protein purification; integration; Expression; aqueous two-phase systems; enzymology; Proteiner; enzymologi;

    Abstract : Popular Abstract in Swedish Människans kropp består av celler som byggs upp av komponenter som DNA, proteiner, lipider och polysackarider. I DNA finns den genetiska informationen lagrad som gör att kroppen kan fungera. Informationen i DNA omvandlas till proteiner som deltager i cellens biokemiska processer. READ MORE
