  2. 2. Macromolecules at Interfaces

    Author : Helén Larsericsdotter; Sven Oscarsson; Jos Buijs; Willem Norde; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Chemistry; Protein; Adsorption; Immobilization; Surface; Surface Plasmon Resonance; SPR; Mass Spectrometry; MS; Differential Scanning Calorimetry; DSC; FT ICR; Lysozyme; Bovine Serum Albumin; BSA; Myoglobin; Globular; Kemi; Chemistry; Kemi;

    Abstract : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). READ MORE

  3. 3. Labelling of various macromolecules using positron emitting 76Br and 68Ga : Synthesis and characterisation

    Author : Ulrika Yngve; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Chemistry; 76Br; Radiobromination; Prosthetic Groups; Macromolecules; Oligonucleotides; 68Ga; PET; Octreotide; Metal Chelates; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : Different prosthetic groups containing a trialkylstannyl- and an electrophilic group have been synthesised and labelled with the accelerator produced 76Br (T1/2=16 h) through oxidative bromination. The labelled prosthetic groups were conjugated to amino-containing macromolecules such as proteins and 5´-modified oligonucleotides. READ MORE

  4. 4. Ions interacting with macromolecules : NMR studies in solution

    Author : Yuan Fang; Istvan Furo; Monika Schönhoff; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; electrophoretic NMR; diffusion NMR; specific ion effects; Hofmeister; ion binding; Kemi; Chemistry;

    Abstract : Specific ion effects, identified for more than hundred years, play an important role in a wide range of phenomena and applications. Several mechanisms such as direct ion interaction with molecules have been suggested to explain these effects, but quantitative experimental evidence remains scarce. READ MORE

  5. 5. Diffusion studies in gels using holographic laser interferometry

    Author : Charlotte Mattisson; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.
