  2. 16. On biomedical electrode technology : with special reference to long-term properties and movement-induced noise in surface electrodes

    Author : Svante Ödman; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aim of the present investigation was to improve the quality of surface electrode measurements. Long-term properties of commercially available ECG-electrodes were studied by investigating polarization potentials, electrode impedance, adhesion and skin reactions during a period of 7 days.

  6. 19. Single-chain antibody construction and functional mapping of the monoclonal antibody TS1 : Its interaction with the antigen and the anti-idiotype

    Author : Patrik Holm; Birgitta Sundström; Per-Åke Nygren; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry; Kemi; Chemistry; Kemi; Biomedicin; Biomedical Laboratory Science;

    Abstract : The aims of this study are to synthesize and produce a single-chain antibody (scFv) of the anti-cytokeratin 8 monoclonal IgG antibody TS1 and to functionally map amino acid residues important for the interaction with its antigen and the anti-idiotypic antibody TS1. The TS1 antibody has been shown to be effective in binding cytokeratin 8 (CK8) expressed in tumors in vivo and is proposed to be useful in immunotargeting and/or immunotherapy. READ MORE
