  • Patent number: 4912254
    Abstract: Pharmaceutically useful optically active .alpha.-arylalkanoic acids or esters, ortho esters, or amides thereof are stereoselectively prepared by contacting an aryl magnesium Grignard reagent with an optically active .alpha.-substituted acyl halide to form the optically active aryl .alpha.-substituted alkyl ketone, which is ketalized and rearranged to the desired optically active .alpha.-arylalkanoic acid or the corresponding ester, ortho ester or amide. In an alternate embodiment, the aryl .alpha.-substituted alkyl ketone is reduced to the corresponding alkanol, which is rearranged to the .alpha.-arylalkanal.

  • Patent number: 4891324
    Abstract: Assay methods are provided for determining an analyte in a sample suspected of containing the analyte. The method is carried out using a composition that includes a conjugate of a first sbp member with a particle. A luminescer is reversibly associated with a nonaqueous phase of the particle. Where the first sbp member is not complementary to the analyte, a second sbp member that is capable of binding to the first sbp member is employed. Unbound conjugate is separated from conjugate that is bound to the analyte or to the second sbp member. A reagent for enhancing the detectability of the luminescer is added and the light emission of the luminescer acted on by the reagent is measured.

  • Patent number: 4886745
    Abstract: The present invention is concerned with novel monoclonal antibodies specific for an antigenic site on a protein characteristic of a human basal cell and a malignant squamous cell. The antibodies do not bind to mesenchymal cells such as fibroblasts and endothelial cells. The protein on the cell surface which binds to one of the antibodies has a molecular weight of about 120,000 as determined by one dimensional gel electrophoresis. The antibodies find use in diagnostic methods such as the detection of malignant cells, e.g., the detection of residual tumor cells in skin subjected to microscopically-controlled surgery.

  • Patent number: 4879215
    Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material.
