    Sammanfattning : Demands for high energy-density batteries have sharpened with the increased use of portable electronic devices, as has the focus global warming is now placing on the need for electric and electric-hybrid vehicles. Li-ion battery technology is superior to other rechargeable battery technologies in both energy- and power-density. LÄS MER

  4. 3. Laboratory methods for investigation of the immunological orchestra in response to pathogens

    Författare :Hanna Carlsson; Ivar Tjernberg; Christina Ekerfelt; Kristina Nilsson Ekdahl; Jorma Hinkula; Matti Sällberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Borrelia; Influenza; Immunology; Immune response; Cellmediated; Serological; Subclinical; ELISA; Luminex; Proximity extension assay;

    Sammanfattning : Laboratory methods used for investigation of immune response often involve collection of whole blood and analysis of different biomarkers in blood components or generated from pathogen stimulation of whole blood or peripheral blood mononuclear cells (PBMC). Methods used to measure biomarkers are for example enzyme-linked immunosorbent assay (ELISA) which measures one biomarker at a time or multiplex assays for example x-unknown, multi-analyte profiling (xMAP) by Luminex or proximity extension assay (PEA), which can measure up to just over 3000 biomarkers at a time.
