  1. 1. High-throughput protein analysis using mass spectrometry-based methods

    Författare :Tove Boström; Sophia Hober; Thomas Laurell; Ole N. Jensen; KTH; []
    Nyckelord :Proteomics; mass spectrometry; affinity proteomics; immunoenrichment; immunoprecipitation; IMAC; screening; protein production; protein purification; ISET; quantification; SILAC; stable isotope standard; antibody validation; Biotechnology; Bioteknologi;

    Sammanfattning : In the field of proteomics, proteins are analyzed and quantified in high numbers. Protein analysis is of great importance and can for example generate information regarding protein function and involvement in disease. Different strategies for protein analysis and quan- tification have emerged, suitable for different applications. LÄS MER

  2. 2. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Författare :Malin Mejàre; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

  3. 3. Targeted proteomics methods for protein quantification of human cells, tissues and blood

    Författare :Fredrik Edfors; Mathias Uhlén; Albert Heck; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; proteomics; mass spectrometry; protein quantification; stable isotope standard; parallel reaction monitoring; immuno-enrichment; Biotechnology; Bioteknologi;

    Sammanfattning : The common concept in this thesis was to adapt and develop quantitative mass spectrometric assays focusing on reagents originating from the Human Protein Atlas project to quantify proteins in human cell lines, tissues and blood. The work is based around stable isotope labeled protein fragment standards that each represent a small part of a human protein-coding gene. LÄS MER

  4. 4. On the Development of Mucin-based Biomaterial Coatings

    Författare :Tomas Sandberg; Karin Caldwell; Jan Carlsson; Thomas Arnebrant; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mucin; Biomaterial; Surface-exposed protein; XPS; Neutrophil; Cell morphology; SEM; QCM-D; Viscoelasticity; Protein-stabilization; HNL; Coating; MG1; BSM; PGM; SEC-MALS-RI; Mucin quantification; Protein adsorption; Ellipsometry; Biomaterials; Biomaterial;

    Sammanfattning : Owing to their key role in mucosal functioning as surface barriers with biospecific interaction potentials, the mucins are interesting candidates for use as surface modifiers in biomaterials applications. In this work, “mild” fractionation procedures were used to prepare mucins of bovine (BSM), porcine (PGM), and human (MG1) origin. LÄS MER

  5. 5. Statistical and machine learning methods to analyze large-scale mass spectrometry data

    Författare :Matthew The; Lukas Käll; Oliver Kohlbacher; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; mass spectrometry - LC-MS MS; statistical analysis; data processing and analysis; protein inference; large-scale studies; simulation; protein quantification; clustering; machine learning; Bayesian statistics; Biotechnology; Bioteknologi;

    Sammanfattning : Modern biology is faced with vast amounts of data that contain valuable information yet to be extracted. Proteomics, the study of proteins, has repositories with thousands of mass spectrometry experiments. These data gold mines could further our knowledge of proteins as the main actors in cell processes and signaling. LÄS MER
