  1. 1. Enthalpy and Entropy in Enzyme Catalysis : A Study of Lipase Enantioselectivity

    Författare :Jenny Ottosson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biocatalysis; enzyme catalysis; Candida antarctica lipase B; enantioselectivity; enthalpy; entropy; CALB; enantiomeric ratio; Bioengineering; Bioteknik;

    Sammanfattning : Biocatalysis has become a popular technique in organic synthesis due to high activity and selectivity of enzyme catalyzed reactions. Enantioselectivity is a particularly attractive enzyme property, which is utilized for the production of enantiopure substances. LÄS MER

  3. 2. Elevers användande av formativ återkoppling i matematik

    Författare :Jenny Green; Kristina Juter; Anders Jönsson; Torgny Ottosson; Lisa Boistrup Björklund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Students are often not satisfied with the feedback they receive, and do not always use it. Providing feedback on student learning has been shown to have a positive effect on learning, and is a key strategy in formative assessment. LÄS MER

  4. 3. Methodology for high-throughput production of soluble recombinant proteins in Escherichia coli

    Författare :Katrin Markland; Gen Larsson; Pär Nordlund; Jenny Ottosson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; high-throughput methodology; recombinant protein production; solubility; productivity; quality; cultivation technology; parallel reactors; Biochemistry; Biokemi;

    Sammanfattning : The aim of this work was to investigate and determine central parameters that can be used to control and increase the solubility, quality and productivity of recombinant proteins. These central parameters should be applicable under the constraints of high-throughput protein production in Escherichia coli. LÄS MER

  5. 4. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations

    Författare :Saara Mikkonen; Åsa Emmer; Leopold Ilag; Jenny Ottosson Takanen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Preconcentration; open microchannel; microchip; MALDI; electrospray ionization; nanoelectrospray; mass spectrometry; computer simulation;

    Sammanfattning : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).
