1. 1. Phylogenetic Inference and Allopolyploid Speciation - A Study of Silene section Physolychnis

   Författare :Anna Petri; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allopolyploidization; next-generation sequencing; Physolychnis; sequence specific primers; Silene; species networks; transcriptomics;

   Sammanfattning : The major theme of this thesis is allopolyploidization, with focus on Silene section Physolychnis. The evolutionary history of an allopolyploid species can be established by inferring the sister relationships of the homoeologous sequences from low copy nuclear markers. LÄS MER

3. 2. Selection of antigens for antibody-based proteomics

   Författare :Lisa Berglund; Mathias Uhlén; Sören Brunak; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epitope; antigen; antibody; affinity; protein; proteome; proteomics; bioinformatics; prediction; primer design; sequence similarity; Bioengineering; Bioteknik;

   Sammanfattning : The human genome is predicted to contain ~20,500 protein-coding genes. The encoded proteins are the key players in the body, but the functions and localizations of most proteins are still unknown. LÄS MER

4. 3. Arrayed identification of DNA signatures

   Författare :Max Käller; Lundeberg Joakim; Mats Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apyrase; allele-specific extension; competitive hybridization; DNA sequencing; genotyping; human papillomavirus HPV ; MC1R; microarray; mutation; p53; protease; Bioengineering; Bioteknik;

   Sammanfattning : In this thesis techniques are presented that aim to determine individual DNA signatures by controlled synthesis of nucleic acid multimers. Allele-specific extension reactions with an improved specificity were applied for several genomic purposes. Since DNA polymerases extend some mismatched 3’-end primers, an improved specificity is a concern. LÄS MER

5. 4. Fatty Acyl Reductases and Fatty Acyl Desaturases. Deciphering the biosynthesis of species-specific moth female sex pheromones from common fatty acids

   Författare :Åsa Hagström; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Moth; pheromone; insect; evolution; fatty acyl desaturase; fatty acyl reductase; endoplasmic reticulum; fatty acid biosynthesis; GFP; heterologous expression; phylogeny; cell factory; lepidoptera;

   Sammanfattning : Moths (Lepidoptera) are dependent on female produced pheromones, chemical signals, for attracting a mate. Pheromones are most commonly made up by saturated and/or unsaturated fatty acid derived alcohols, acetates, and/or aldehydes that are produced by a set of enzymes in the female pheromone gland.

7. 5. The use of molecular techniques for identification of genetic divergence in transplantation : with special reference to MHC genes and HLA typing

   Författare :Henrik Zetterquist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Clinical transplantation; HLA; histocompatibility testing; PCR; allele-specific amplification; sequence-specific primers; bone marrow transplantation; mixed chimerism; minimal residual disease; acute lymphoblastic leukemia;

   Sammanfattning : Transplantation immunology basically deals with the immune mechanisms that lead to rejection of transplanted tissues. Lymphocytes are the key mediators of graft rejection. At the time for this observation, the genetic loci responsible for histocompatibility between individuals of the same species were already identified in the mouse. LÄS MER
