2. 1. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS

   Author : Patrik Önnerfjord; Reumatologi och molekylär skelettbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein identification; microchip IMER; microdispensing; MALDI-TOF MS; fluorescence polarization; flow immunoassay; pesticide immunoassays; phenol biosensor; restricted access media; SPE; Analytical chemistry; Analytisk kemi;

   Abstract : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

4. 2. Analysis of proteins related toautoimmune and inflammatorydiseases with focus on newenrichment methodologies and MALDI-TOF MS

   Author : Yuye Zhou; Åsa Emmer; Margret Thorsteinsdottir; KTH; []
   Keywords : Protein; Glycopeptide; IgG; Osteopontin; Enrichment; Digestion; Separation; Microchip; MALDI-TOF MS; Kemi; Chemistry;

   Abstract : Proteins have been widely studied in biological sample analysis due to the association with diseases. In the present project, method and technique development was carried out on the analysis of two proteins, immunoglobulin G (IgG) and osteopontin (OPN). READ MORE

5. 3. Sampling and Selective Detection of Peptides and Proteins Emphazing Microdialysis,Bio-recognition Assays and MALDI-TOF MS

   Author : Sven Kjellström; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cyclodextrines; protein identification; m-dispenser; push-pull microdialysis; microdialysis sampling; MALDI-TOF MS; Interleukin-8; Flow immuno assays; Interleukin-10; Analytical chemistry; Analytisk kemi;

   Abstract : The use of microdialysis sampling and flow immunochemical detection as well as MALDI-TOF MS for peptide and protein analysis is described. Sampling of peptides and smaller proteins was investigated with different membranes. READ MORE

6. 4. Improved mass accuracy in MALDI-TOF-MS analysis

   Author : Martin Kempka; Johan Roeraade; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; MALDI; mass spectrometry; mass accuracy; peak picking; ion formation; proteins; peptides; chip; sample handling; sensitivity.; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Abstract : Mass spectrometry (MS) is an important tool in analytical chemistry today, particularly in the field of proteomics where identification of proteins is the central activity. The focus in this thesis has been to improve the mass accuracy of MS-analyses in order to improve the possibility for unambiguous identification of proteins. READ MORE

7. 5. Haemophilus influenzae – typing, epidemiology and beta-lactam resistance

   Author : Viktor Månsson; Malmö Klinisk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; beta-lactam resistance; beta-lactams; BLNAR; capsule typing; clonal; Haemophiilus influenzae; Hib; MALDI-TOF MS; MLST; NTHi; serotyping; virulence; epidemiology;

   Abstract : Haemophilus influenzae is a common cause of respiratory tract infections such as acute otitis media (AOM), exacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia. The species is subdivided into encapsulated and non-encapsulated strains, designated type a-f and nontypeable H. influenzae (NTHi), respectively. READ MORE
