  1. 11. Intracellular vesicles induced by monotopic membrane protein in Escherichia coli

    Författare :Hanna M. Eriksson; Åke Wieslander; Meta Kuehn; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; intracellular vesicles; Escherichia coli; glycosyltransferase; overexpression; optimization; detergent; screening; lipid composition; Biochemistry; Biokemi; Biochemistry; biokemi;

    Sammanfattning : The monotopic membrane protein alMGS, a glycosyltransferase catalyzing glucolipid synthesis in Acholeplasma laidlawii, was overexpressed in Escherichia coli. Optimization of basic growth parameters was performed, and a novel method for detergent and buffer screening using a small size-exclusion chromatography was developed. LÄS MER

    Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. LÄS MER
