  • Patent number: 6270746
    Abstract: The invention provides an IgE and antigen-specific screening assay for use in identifying agents which suppress the IgE mediated immune response to antigen. The assay is performed in vivo in animals which hyper respond to antigen by producing exaggerated levels of IgE. The animals are sensitized to an antigen during a specific window of sensitivity which closes a day after the animal has been treated to produce the IgE hyper responsive phenotype. The screening assay is performed in the animals by treating them with a candidate IgE suppressor agent in conjunction with further immunization made after closure of the window of sensitivity defined by the invention. Positive results (indicating that the candidate agent has IgE suppressive activity) are obtained in the assay through measurement of a decline in antigen-specific IgE in the animal following its treatment with the candidate agent.

  • Patent number: 4943522
    Abstract: A method and apparatus for conducting specific binding pair assays, such as immunoassays, is described. A porous membrane capable of non-bibulous lateral flow is used as assay substrate; a member of the binding pair is affixed in an indicator zone defined in the substrate. The sample is applied at a position distant from the indicator zone and permitted to flow laterally through the zone; any analyte in the sample is complexed by the affixed specific binding member, and detected. A novel method of detection employs entrapment of observable particle in the complex. Blood is a particularly preferred sample as the red blood cells can be used as the observable particles for detection of the complex.
