  • Publication number: 20150144492
    Abstract: Electrophoresis gel cassette comprising a first and a second face wall member and one or more side wall members, defining a gel compartment for a gel member with a first and second face, wherein the first face wall member has high gel adhesion compared to the second face wall member, whereby a gel member molded in the cassette will stay attached to the high gel adhesion face wall member when the cassette is opened, and wherein the first face wall member is provided with at least one removable section to expose a section of the first face of the gel member, the removable section of the first face wall member having lower gel adhesion compared to the non-removable part of the first face wall member.

  • Publication number: 20140227136
    Abstract: A Surface Plasmon Resonance (SPR) biosensor system comprising: a SPR sensor surface, an illumination unit arranged to direct a wedge shaped beam of light at a line shaped detection area on the SPR sensor surface transverse to the direction of propagation of light, and a detection unit with detection optics for directing light reflected from the SPR sensor surface onto a two-dimensional optical detector unit such that the angle of reflection is imaged along one dimension and the width of the detection area along the other, wherein the illumination unit is arranged to selectively direct the wedge shaped beam of light at two or more spaced apart line shaped detection areas on the SPR sensor surface transverse to the direction of propagation of light.

  • Publication number: 20140219871
    Abstract: A flow cell unit to be docked against a flat lid surface to form a closed flow cell arrangement, the flow cell unit comprising a top surface with protruding walls of elastic material defining three or more adjacent elongated flow channels, each flow channel comprises a first fluid port and a second fluid port, wherein the walls separating adjacent flow channels comprises a valve section of reduced height, thereby allowing selective opening and closing of a flow path transverse to the elongated flow channels by controlling the docking force between flow cell and the lid surface to an open docking state and a closed docking state respectively.

  • Patent number: 8021626
    Abstract: Methods and devices are provided for controlling a fluid flow over a sensing surface within a flow cell. The methods employ laminar flow techniques to position a fluid flow over one or more discrete sensing areas on the sensing surface of the flow cell. Such methods permit selective sensitization of the discrete sensing areas, and provide selective contact of the discrete sensing areas with a sample fluid flow. Immobilization of a ligand upon the discrete sensing area, followed by selective contact with an analyte contained within the sample fluid flow, allows analysis by a wide variety of techniques. Sensitized sensing surfaces, and sensor devices and systems are also provided.
