  1. 11. Molecular and functional characterization of the insect hemolymph clot

    Författare :Malin Lindgren; Ulrich Theopold; Andreas Vilcinskas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innate immunity; hemolymph coagulation; transglutaminase; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : All metazoans possess an epithelial barrier that protects them from their environment and prevents loss off body fluid. Insects, which have an open circulatory system, depend on fast mechanism to seal wounds to avoid excessive loss of body fluids. LÄS MER

  3. 12. Hemolin, a versatile immune protein from the Cecropia moth

    Författare :Raul Bettencourt; Kenneth Söderhäll; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Sammanfattning : Insects have become useful models for the study of innate immune mechanisms, due to their lack of antibodies and receptors involved in adaptive immune response. However, the molecules and mechanisms involved in primordial immune recognition are still poorly understood. LÄS MER

  4. 13. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

    Författare :Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). LÄS MER

  5. 14. RECOMBINANT PEROXIDASES AND XYLANASES: I. Cloning and production of a peroxidase from horseradish II. Characterisation of functional domains of thermostable xylanases from Rhodothermus marinus

    Författare :Eva Bartonek Roxå; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amorphous cellulose; xylan; CBD; carbohydrate binding domains; insect cells; Baculovirus; catalytically active; recombinant horseradish peroxidase; HRP-n; PASC; beta-glucan; Biotechnology; Bioteknik;

    Sammanfattning : Part I: Plant peroxidases are useful in many areas of application e.g. as tracer enzymes for clinical applications and in biosensors as well as for industrial purposes like in waste water treatment and bleaching processes. A gene encoding a new, neutral horseradish peroxidase isoenzyme, HRP-n, was isolated. LÄS MER

  7. 15. Impact of autocrine factors on physiology and productivity in Trichoplusia ni serum-free cultures

    Författare :Ulrika Eriksson; Lena Häggström; Per Berglund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Trichoplusia ni; High Five; insect cells; BEVS; serum-free medium; yeast extract; conditioned medium; autocrine regulation of proliferation; growth factors; cell cycle; metalloproteinase; specific productivity; Bioteknik; Bioengineering; Bioteknik;

    Sammanfattning : The aim of this study was to increase the understanding of the mechanisms regulating cell proliferation and recombinant protein production in serum-free cultures of Trichoplusia ni (T. ni) insect cells.Conditioned medium (CM) was shown to contain both stimulatory and inhibitory factors (CM factors) influencing cell growth.
