  6. 14. Na,K-ATPase as signaling transducer

    Author : Juan Li; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It is now generally agreed that Na,K-ATPase (NKA), in addition to its role in the maintenance of Na+ and K+ gradients across the cell membrane, is a signal transducer. Our group has identified a novel signaling pathway where NKA interact with IP3R to form a signaling microdomain. READ MORE

  7. 15. Affinity biosensors based on a capacitive transducer

    Author : Christine Berggren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-assembled monolayers; capacitance; heavy metal ion; non-labeled; nucleic acid; DNA biosensor; Biosensor; immunosensor; Analytical chemistry; Analytisk kemi;

    Abstract : Capacitive biosensors were developed for several analytes such as hormones, interleukines, viruses and heavy metal ions. The sensing surfaces were prepared by immobilizing the biorecognition element to self-assembled monolayers (SAMs) on gold. SAMs form spontaneously on gold by adsorption of thiols, sulfides or disulfides. READ MORE
