  2. 1. Genetically Engineered Plants: Improved stress tolerance, growth and facilitated protein purification

    Author : Gösta Lilius; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; glycine betaine; gene; freezing; flooding; drought; dicoteledones; desiccation; compatible solutes; cold; choline dehydrogenase; chill; CDH; betaine; betA; alkaloids anoxia; affinity purification; affinity tags; handles; hemoglobin; hypoxia; low temperatu; Biotechnology; Bioteknik;

    Abstract : Heterologous genes were expressed in plants in which the overall goal was to increase the value of the final crop. Various aspects were explored and evaluated, such as improving the stress tolerance, enhancing the availability of oxygen in growing cells and producing rare proteins with increased degrees of purity.

  5. 3. Optimisation of diagnostic PCR a study of PCR inhibitors in blood and sample pretreatment

    Author : Waleed Abu Al-Soud; Avdelningen för medicinsk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; virology; bacteriology; Microbiology; AmpliTaq Gold; Amplification facilitators; Betaine; Blood culture medium; Blood; BSA; cheese; faeces; gp32; Haemoglobin; Ions; Immunoglobulin G; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : PCR is widely employed as a rapid, sensitive and specific molecular diagnostic technique in clinical diagnosis, environmental investigations and for monitoring biotechnical processes. However, the full potential of diagnostic PCR is limited, in part, by the presence of PCR-inhibitory substances in biological samples. READ MORE

  6. 4. Abiotic Stress Tolerance. Metabolic and Physiological Effects of Compatible Solutes and Calmodulin on E. coli and Tobacco

    Author : Jenny Lindberg; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Abiotic stress; compatible solutes; osmotic stress; osmoprotectants; trehalose; calmodulin; E. coli; N. tabacum; genetic engineering; Biotechnology; Bioteknik; Biochemistry; Metabolism; Biokemi; metabolism; glycine betaine;

    Abstract : In their natural habitats, bacteria and plants can be exposed to abiotic stresses such as drought, high salt concentrations and freezing, which are factors limiting their capacity for growth and proliferation. To withstand environmental stresses, they have evolved specific stress responses. READ MORE

  7. 5. Cleavable Cationic Gemini Surfactants
