  1. 1. Interaction Between Microgels and Oppositely Charged Proteins

    Författare :Christian Johansson; Per Hansson; Brian Saunders; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; microgel; protein; uptake; distribution; core-shell; colloidal stability; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.

  2. 2. Eosinophil Cationic Protein : Expression Levels and Polymorphisms

    Författare :Jonas Byström; Helene Rosenberg; Uppsala universitet; []
    Nyckelord :Medical sciences; Eosinophils; Neutrophils; Monocytes; Macrophages; mRNA; eosinophil cationic protein; DNA; polymorphism; Hodgkin Lymphoma; asthma; allergy; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : The eosinophil cationic protein (ECP) is usually associated with the eosinophil granulocyte. In this thesis the presence and production of this protein has been studied in two other cells. The circulating monocyte was found to contain ECP mRNA and small amounts of ECP, one thousand times less than that found in the eosinophil. LÄS MER

  3. 3. Tailoring of Biomaterials using Ionic Interactions : Synthesis, Characterization and Application

    Författare :Björn Atthoff; Jöns Hilborn; Tim Bowden; Mats Andersson; Uppsala universitet; []
    Nyckelord :Chemistry; biodegradable polymers; ionomer; water uptake; protein delivery; protein adsorption; protein membrane; cell seeding efficiency; amphiphillic; inner structure; polarized membrane; Kemi;

    Sammanfattning : The interactions between polymers and components of biological systems are an important area of interest within the fields of tissue engineering, polymer chemistry, medicine and biomaterials. In order to create such a biomimetic material, it must show the inherent ability to reproduce or elicit a biological function. LÄS MER

  4. 4. Enhancing membrane and secretory protein production yields in Escherichia coli

    Författare :Zhe Zhang; Jan-Willem de Gier; Claes von Wachenfeldt; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; recombinant protein production; Escherichia coli; membrane protein; secretory protein; strain engineering; biokemi; Biochemistry;

    Sammanfattning : Proteins fulfill essential functions in living cells. To produce sufficient amounts of a protein is essential to study the structure and function of a protein, or to use it for medical purposes. Escherichia coli is a Gram-negative bacterium that is widely used for recombinant protein production. LÄS MER

  5. 5. Interactions of the Cell-Penetrating Peptide Penetratin with Model Membranes and Live Cells

    Författare :Daniel Persson; Chalmers University of Technology; []
    Nyckelord :antisense; antennapedia homeodomain; delivery vector; cell-penetrating peptide; protein transduction; uptake; membrane translocation; penetratin; confocal microscopy; vesicle;

    Sammanfattning : The delivery of large, hydrophilic molecules, such as proteins and oligonucleotides, to the cytoplasm and nucleus of cells is problematic due to their generally low plasma membrane permeability. With the identification of a number of cell-penetrating peptides, capable of mediating non-endocytotic, intracellular delivery of macromolecular cargos, this obstacle now seems surmountable. LÄS MER
