  5. 4. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate

    Författare :Andrea Schmid; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bulk polymerization; N; hydrophilic gels; separation; methyl methacrylate; hydrophobic networks; acrylamide; porous networks; Suspension; N -methylene-bis-acrylamide; chemically crosslinked networks; dry gels; polysaccharide standards; distilled water; copolymerization; trimethylolpropane trimethacrylate;

    Sammanfattning : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. LÄS MER

  7. 5. Systemic RNAi Relies on the Endomembrane System in Caenorhabditis elegans

    Författare :Yani Zhao; Andrea Hinas; Staffan Svärd; Simon Tuck; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic RNAi; RNAi inheritance; late endosomes MVBs; SID-5; SEC-22; SYX-6; C12D8.1; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The membrane system of a eukaryotic cell is a large and complex system handling the transport, exchange and degradation of many kinds of material. Recent research shows that double-stranded RNA (dsRNA) mediated gene silencing (RNA interference) is a membrane related process. LÄS MER
