    摘要: A highly sensitive and specific monoclonal-immuno-radiometric assay (M-IRMA) for hCG, using monoclonal antibodies (Mabs) directed against a 37-amino acid synthetic polypeptide analogous to the carboxyl terminus (CTP) of beta-hCG. Accordingly, in one embodiment, a method is described for the determination of human chorionic gonadotrThe present invention was made utilizing funds of the United States Government. The U.S. government is therefore granted a royalty-free, non-exclusive, world wide, paid-up license in this invention.

    摘要: A method for the determination of a free protein subunit of a quaternary protein in a sample, which comprises:(a) contacting a sample with a first immunological binding partner which is or will be bound to a carrier, wherein the first immunological binding partner binds epitopic determinants bindable only on the free protein subunit;(b) incubating the components of step (a) for a period of time and under conditions sufficient to form an immune complex between the free protein subunit, the first immunological binding partner, and the carrier;(c) separating the carrier of step (b) from the sample;(d) adding to the carrier of step (c), a detectably-labeled second immunological binding partner, wherein the second immunological binding partner binds epitopic determinants bindable on both the free protein subunit and the quaternary protein; and(e) determining the detectably-labeled second immunological binding partner in the carrier or in liquid phase.

    摘要: The invention relates to an immunometric assay for a multivalent antigen in a sample which comprises forming a complex of the antigen together with multiple immobilized monoclonal antibodies against different epitopes of the antigen and with a detectably labeled soluble monoclonal antibody which is identical to one of the multiple immobilized antibodies. The labeled antibody associated with the complex is separated from the remaining soluble antibody and the detectably labeled antibody associated with the complex or unassociated with the complex is detected. Any one of the multiple immobilized monoclonal antibodies shows, by itself, substantially less binding towards the antigen in the immunometric assay, when used with itself or another monocolonal antibody in soluble labeled form, than when used with the multiple immobilized antibodies in combination.

    摘要: A process for detecting malignant transformation of cells involves detecting the overexpression of the products of the &bgr;3, &bgr;5, &bgr;8 and &bgr;9 genes, which encode the hCG&bgr; subunit, relative to their expression in nonmalignant cells. A kit for diagnosing an hCG- or an hCG fragment-secreting cancer includes an assembly of polypeptides covering at least a part of the primary sequence of hCG. The use of a polypeptide corresponding to at least one portion of the primary sequence of hCG for producing a composition useful in hCG- or hCG fragment-secreting cancer immunotherapy is also disclosed.
