  1. 1. Microgel Interactions with Peptides and Proteins Consequence of Peptide and Microgel Properties

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ronja Widenbring; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

  2. 2. Cell-penetrating peptides and bioactive cargoes Strategies and mechanisms

    University dissertation from Stockholm : Institutionen för neurokemi

    Author : Kalle Kilk; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; delivery; Peptide nucleic acid; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi Biokemi;

    Abstract : The cell membrane is an impermeable barrier for most macromolecules. Recently discovered cell-penetrating peptides (CPPs) have gained lot of attention because they can cross the membrane, and even more, carry cargoes with them. How CPPs enter cells is still not clear, while the delivery of different cargoes has been convincingly shown. READ MORE

  3. 3. Antimicrobial activity of human seminal plasma and seminal plasma proteins

    University dissertation from Lund University

    Author : Anneli Edström; Lunds universitet.; Lund University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibacterial peptides; semenogelin; antifungal peptides; seminal plasma; antimicrobial peptides; vaginal pH; beta-microseminoprotein; peptides;

    Abstract : Seminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. READ MORE

  4. 4. Interaction Between Microgels and Oppositely Charged Peptides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helena Bysell; Uppsala universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. READ MORE

  5. 5. Interfacing HPLC with MALDI- and ESI-MS for Automated High Sensitivity Analysis of Proteins and Peptides

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Tasso Miliotis; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phosphorylation; automated; ZAP-70; peptides; proteins; comprehensive; multidimensional; two-dimensional; piezoelectric; microdispenser; flow-through; ESI-MS MS; Capillary HPLC; MALDI-TOF MS; Analytical chemistry; Analytisk kemi;

    Abstract : The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides.
