Abstract: A fabric-based item may include fabric layers and other layers of material. An array of electrical components may be mounted in the fabric-based item. The electrical components may be mounted to a support structure such as a flexible printed circuit. The flexible printed circuit may have a mesh shape formed from an array of openings. Serpentine flexible printed circuit segments may extend between the openings. The electrical components may be light-emitting diodes or other electrical devices. Polymer with light-scattering particles or other materials may cover the electrical components. The flexible printed circuit may be laminated between fabric layers or other layers of material in the fabric-based item.

Abstract: Disclosed are immunological methods and materials for detection of antigens associated with breast or prostate cancer disease states. Presently preferred antibody preparations (e.g., PR92 monoclonal antibodies produced by hybridoma cell line ATCC HB 9390) are employed in immunoassays performed on patient body fluids and for purification of tumor-associated antigen compositions.

Abstract: This invention relates to an immunoassay for carcinoembryonic antigen in plasma or sera. Heat-treating the plasma or serum provides a supernatant which is incubated with a solid support having carcinoembryonic antigen antibody adsorbed thereto. Subsequently, the solid support is incubated with a labeled carcinoembryonic antigen antibody. The labeled antibody on the solid support is measured and compared to standards.

Abstract: This application discloses a method for diagnosing cancer by employing any of various immunochemical procedures to detect elevated levels of anti-(blood group T antigen) antibodies in a biological sample.

Abstract: An improvement in a method for the separation of carcinoembryonic antigen (CEA) from a plasma sample preparatory to conducting an assay for said antigen is disclosed.
