  2. 1. Influence of Escherichia coli feedstock properties on the performance of primary protein purification

    Author : Mattias Råvik; Andres Veide; Åsa Emmer; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Downstream processing; cell surface properties; surface plasmon resonance; contact angle measurements; microelectrophoresis; aqueous two-phase partitioning; filtration; EBA adsorbents; high-pressure homogenisation; Biochemistry; Biokemi;

    Abstract : Abstract The aim of the present study was to increase the understanding of how the cell surface properties affect the performance of unit operations used in primary protein purification. In particular, the purpose was to develop, set up and apply methods for studies of cell surface properties and cell interactions. READ MORE

  4. 2. Versatile Implementations of an Improved Cell-Free System for Protein Biosynthesis : Functional and structural studies of ribosomal protein L11 and class II release factor RF3. Novel biotechnological approach for continuous protein biosynthesis

    Author : Lamine Bouakaz; Måns Ehrenberg; Richard Buckingham; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Protein synthesis; translation termination; ribosome; release factor; cell-free system; missense error; gel filtration; affinity chromatography; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Advances in genetics, proteomics and chromatography techniques have enabled the successfully generation of a cell-free bacterial translation system composed of highly pure and active components. This system provided an ideal platform for better elucidating the mechanism of each individual step of the prokaryotic protein biosynthesis and the function of the translation factors involved in the process.

  6. 4. Dynamics of the glomerular filtration barrier - Physiological and pathophysiological aspects

    Author : Josefin Axelsson; Njurmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glomerular filtration barrier; Glomerular permeability; Microalbuminuria; Albumin; Ficoll; Sieving Coefficient; Rats;

    Abstract : The dynamic properties of the glomerular filtration barrier (GFB) are of fundamental importance for the understanding of the physiology and pathophysiology of microalbuminuria and proteinuric diseases. In the studies of this doctoral thesis the properties of the rat glomerular filtration barrier were investigated under resting conditions and following a number of challenges using highly sensitive gel filtration chromatography (HPSEC) detection of FITC-Ficoll in serum and urine.

  7. 5. Galactoglucomannan recovery from softwood spent sulfite liquor: Challenges, process design and techno-economic evaluations

    Author : Basel Al-Rudainy; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galactoglucomannan; Lignin; Lignosulfonates; Lignin-carbohydrate-complexes; Membrane filtration; Dead-end filtration; Precipitation; Adsorption;

    Abstract : In the production of pulp and paper, water-soluble components, such as hemicellulose, monosaccharides, and lignin, are released and accumulate in the process water. The process water is usually concentrated and incinerated for heat generation and the recovery of pulping chemicals, such as in the Kraft and sulfite processes. READ MORE
