    摘要: A method of detecting a target moiety comprising the steps of (a) providing an antibody specific to the target, (b) saturating the binding sites of the antibody with a labelled form of the target, (c) flowing a liquid containing the target past the saturated antibody, thereby (d) allowing the target to displace the labelled antigen, and (e) detecting the displaced labelled antigen with a detector for the label.Also, the invention is accomplished by a flow immunosensor comprising: a liquid flowing through the immunosensor for moving a sample through the immunosensor; a receiving means for introducing the sample to the liquid stream; a flow control means for moving the liquid stream through the immunosensor; an exchanger connected to the sample receiving means in which the sample is brought in contact with labelled antigens of the target and whereby any target present is allowed to displace the labelled antigen; a detection apparatus connected to the exchanger for detecting any labelled antigen which is released; and a disposal means connected to the detection apparatus for disposing of or collecting of waste coming from the detection apparatus.

    摘要: Target moiety is detected by (a) providing an antibody specific to the target, (b) saturating the binding sites of the antibody with a labelled form of the target, (c) flowing a liquid containing the target past the saturated antibody, thereby (d) allowing the target to displace the labelled antigen, and (e) detecting the displaced labelled antigen with a detector for the label. This assay is performed by a flow immunosensor comprising: a liquid flowing through the immunosensor for moving a sample through the immunosensor; a sample receiver for introducing the sample to the liquid stream; a flow controller for moving the liquid stream through the immunosensor; an exchanger connected to the sample receiving area in which the sample is brought in contact with labelled antigens of the target and where any target present is allowed to displace the labelled antigen; a detection apparatus connected to the exchanger for detecting any labelled antigen which is released; and a disposal means connected to the detection apparatus for disposing of or collecting of waste coming from the detection apparatus.

    摘要: Displacement assays, under non-equilibrium conditions, are performed by flowing a liquid sample through a membrane having binding elements with binding sites saturated with a labelled form of the analyte. Analyte in the sample displaces, under non-equilibrium conditions, the labelled form of the analyte from the membrane. The displaced labelled form of the analyte may then be detected.

    摘要: A method of biochemical identification by: providing a plurality of capture species bound to one or more substrates and suspected of having one or more biological targets affinity bound to at least one capture species; detecting which capture species contain bound biological targets to generate a binding pattern; and identifying the biological target based on the binding pattern. The capture species are independently selected from the group consisting of antimicrobial peptides, cytotoxic peptides, antibiotics, and combinations thereof. A device having the capture species bound to the substrates. At least two of the capture species are capable of multi-specific binding to one or more biological targets and may have overlapping but not identical affinity properties.

    摘要: A magnetic bead trap-and-mixer includes a channel having openings at opposing ends, and a rotor adjacent to the channel and comprising a permanent magnet, wherein the rotor is adapted to apply a magnetic field to the channel of sufficient strength to direct the movement of magnetic beads therein. In aspects, the channel is straight and/or has narrowed end. In further aspects, the rotor generates in the channel areas of areas of strong magnetic fields alternating with areas of very weak magnetic fields and the strong magnetic fields extend entirely across the channel.
