Detecting Cell Physiological Changes in Response to Light Induced Ion Channel Opening

Application Notes /

Abstract Light-gated ion channels allow modifying transmembrane ion fluxes and consequently,the intracellular distribution of ions without applying electric fields or introducing stimulating electrodes. Channelrhodopsyn is a Na+ and Ca2+ permeable cation channel, which opens in response to illumination at wavelengths of 460-490 nm. The influx of Na+ and Ca2+ depolarizes the cells and results in

Label-free immunosensor for herbicide trifluralin detection with OWLS

Application Notes /

Abstract Acting as a potent microtubule inhibitor, the dinitroaniline herbicide trifluralin has been used in agricultural applications as a selective, pre-emergence herbicide in various plant cultures including grain, crops, vegetables, fruits and nuts. In recent years, the compound is a subject to increasing toxicological and environmental concerns. OWLS offered a highly sensitive label free method

Label-free immunosensor for HSP70 detection

Application Notes /

Abstract OWLS immunosensor offers a real time label-free detection of heat shock protein, HSP70 (molecular weight of70 kDA). For biosensing monoclonal antibodies raised against HSP70 protein under investigation were used. Toform regenerable sensor surface, the waveguide sensor surface was modified with amino group and sensitized byimmobilizing antibody/antigen molecules covalently to the surface. Label-free immunosensor for

Test measurement of label-free immunosensor using BSA-antiBSA model molecule pair (GA)

Application Notes, News /

In the case of glass type metal oxide surfaces suchas SiO2-TiO2, mainly hydroxyl groups are present, which offer relatively few possibilities for covalent immobilization of biomolecules. To widen the circle of covalent coupling methods, the surface of the waveguide has to be modified by silanization using reactive silane reagents for introducing functionalgroups of all sorts
