  1. 1. Development and Evaluation of Preparation Methods for the Analysis of Cell Membranes Using Time-of-Flight Secondary Ion Mass Spectrometry

    Författare :Jakob Malm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; salt; cryofixation; TOF-SIMS; supported phospholipid bilayer; freeze drying; vacuum; cells; POPC; glutaraldehyde;

    Sammanfattning : The aim of this work was to evaluate and develop methods for preparing dry samples for TOF-SIMS analysis of cell membranes. For correct interpretation of the analysis data, an understanding of the effects that the preparation method has on the morphology and chemical structure of the sample must first be obtained.

  3. 2. Targeting to EGF receptors : Preparation and experimental analysis of end-end coupled mEGF-dextran conjugates

    Författare :Qinghai Zhao; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; Biomedical Radiation Science; biomedicinsk strålningsvetenskap;

    Sammanfattning : Targeted tumor therapy is to deliver cytotoxic agents selectively to tumor cells. By such delivery, normal tissues receive minimal damage while a therapeutical effect is achieved in tumor. A targetingsystem can be constructed by conjugating a tumor-seeking molecule and toxic agents via a carrier. LÄS MER

  4. 3. Glycosylation of microsomal proteins and their relationship to peroxisomes

    Författare :Eeva-Liisa Appelkvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The distribution of glycoproteins in rough and smooth microsomes and Golgi membranes was studied using proteolytic treatment of intact vesicles. About half of the protein-bound sugar residues could be removed by this treatment, indicating the presence of glycoproteins on both surfaces of the membrane. LÄS MER

  5. 4. Immunocytochemical visualization of cathepsin D during oxidative stress

    Författare :Karin Roberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Cathepsin D is the major aspartic protease in lysosomes, and it is found in almost all animal cells. In the present studies, a pre-embedding immunocytochemical method was used to visualize cathepsin D in cultured cells. The protein can be detected at both light and electron microscopic levels by neutral-pH silver enhancement of ultrasmall (0. LÄS MER

  7. 5. Fabrication of Functional Molecularly Imprinted Materials using Nanoparticle Building Blocks

    Författare :Changgang Xu; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymers; magnetic susceptibility; click chemistry; PFPA; Pickering emulsion; chemical conjugation;

    Sammanfattning : Molecularly imprinted polymers (MIPs) have attracted great interest in many applications including bioseparation, chemical sensing, catalysis, drug delivery, etc. Recently, molecularly imprinted nanoparticles have become accessible due to a number of synthetic methods that have been developed.
