  2. 1. Identification and Characterization of Peptides and Proteins using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    Author : Magnus Palmblad; Ole Nørregaard Jensen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Peptide; protein; peptide mass fingerprinting; identification; sequencing; protein structure; non-covalent interaction; modification; electrospray ionization; liquid chromatography; capillary electrophoresis; electron capture dissociation; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyloid β-peptide; Alzheimer’s disease.; Materialvetenskap; Materials science; Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Mass spectrometry has in recent years been established as the standard method for protein identification and characterization in proteomics with excellent intrinsic sensitivity and specificity. Fourier transform ion cyclotron resonance is the mass spectrometric technique that provides the highest resolving power and mass accuracy, increasing the amount of information that can be obtained from complex samples.

  4. 2. Effects of fusion tags on protein partitioning In aqueous two-phase systems and use in primary protein recovery

    Author : Cynthia Hassinen; KTH; []
    Keywords : E. coli; Aqueous two-phase systems; Fusion proteins; Hydrophobic interaction chromatography; Expanded bed adsorption; Beta-galactosidase; Klenow polymerase; Z-domain; Peptide tags;

    Abstract : The two techniques aqueoustwo-phase partitioning and expanded bed adsorption that bothare suitable for primary protein recovery were studied. Most ofthe work was focused on partition in aqueous two-phase systemsand in particular on the possibility to effect the partitionbehaviour by fusion of short peptide tags or protein domains tothe target protein.

  5. 3. Protein Surfaces Probed by Aqueous Two-phase Partitioning

    Author : Kristina Berggren; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; partitioning; Aqueous two-phase systems; protein surface; peptide; Biochemistry; amino acid residue; Biokemi;

    Abstract : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. READ MORE

  6. 4. PNA and affinity protein tools for selective tumor targeting of radiopharmaceuticals

    Author : Hanna Tano; Amelie Eriksson Karlström; Per-Åke Nygren; Dario Neri; KTH; []
    Keywords : Cancer therapy; targeted radionuclide therapy; affinity proteins; Affibody molecules; CD38; GRPR; HER2; nanobody; peptide; PNA; RM26; pretargeting; Cancerterapi; radionuklid terapi; affinitetsproteiner; affibody molekyler; CD38; GRPR; HER2; nanobody; peptid; PNA; RM26; pretargeting; Biotechnology; Bioteknologi;

    Abstract : Targeted radiotherapy of cancer intends to selectively deliver cytotoxic radionuclides to tumor cells. Affinity proteins of various kinds are explored for this task, and depending on the affinity protein used, different challenges arise. READ MORE

  7. 5. Analysis of Complex Biological Samples using Liquid Chromatography-Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    Author : Margareta Ramström; Jonas Bergquist; Per Håkansson; Karin Markides; Carol Robinson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; mass spectrometry; liquid chromatography; protein; proteomics; peptide; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyotrophic lateral sclerosis; electrospray ionization; electron capture dissociation; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Studies of protein and peptide expression are vital in order to understand complex biological systems. As demonstrated in this thesis, on-line packed capillary liquid chromatography-Fourier transform ion cyclotron resonance mass spectrometry (LC-FTICR MS) is a useful analytical tool for such studies.
