  1. 6. Expression and processing of cecropin and attacin using a baculovirus vector

    Författare :Marianne Hellers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : The cecropins and attacins are two antibacterial peptides induced uponimmunization in the moth Hyalophora cecropia. They are both synthesized aspreproproteins that are processed and post-translationally modified along the exportpathway. LÄS MER

  3. 7. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A

    Författare :Ann Lövgren; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. LÄS MER

  4. 8. Studies on O-glycosylation of mucin-type proteins and their binding to antibodies, bacterial toxins and viral receptors

    Författare :Stefan Gaunitz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Carbohydrates are ubiquitous on the surface of all cells in mammals where they are involved in interactions with the surroundings (extracellular matrix), other cells (including self and non-self) and microbes (bacteria and virus). Carbohydrate-protein interactions in nature are often mediated via multivalent binding where the combined strength of multiple receptor- ligand interactions results in a binding that is highly specific and strong.

  5. 9. Physiology and productivity of serum-free Spodoptera frugiperda Sf9 insect cell cultures

    Författare :Eva Lindskog; Lena Häggström; Spiros N. Agathos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Animalcellteknologi; Bioengineering; Bioteknik;

    Sammanfattning : The objective of this study was to investigate the mechanisms and factors controlling growth and proliferation in serum-free Spodoptera frugiperda Sf9 cultures as well as the implications of these factors for protein production in the baculovirus expression system. The physiology of recently thawed, low passage (Lp) Sf9 cultures, were compared to high passage (Hp) cultures at p>100. LÄS MER
