    摘要: A chemiluminescent assay to determine the presence and/or amount of one or more labeled target molecules in a sample is described in which the surface layer of a solid support is contacted with a composition comprising first and second chemiluminescent substrates capable of being activated by first and second enzymes, respectively. A plurality of probes are disposed on the surface layer in discrete areas. At least some of the probes are bound to a first enzyme conjugate comprising the first enzyme and at least some of the probes are bound to a second enzyme conjugate comprising the second enzyme. The resulting chemiluminescent signals are then detected. The method can be used to compare two biological samples (e.g., mRNA populations from different cells) on the same support surface or to provide a chemiluminescent control signal for normalizing chemiluminescent assay data from a biological sample.

    摘要: Chemiluminescent assays to determine the presence and/or amount of one or more labeled analytes in a sample are described wherein a solid support is contacted sequentially with first and second chemiluminescent substrates each of which are capable of being activated by an enzyme and the resulting chemiluminescent signals are detected. A plurality of probes are disposed on a surface layer of the solid support in a plurality of discrete areas. Some of the probes are bound to a conjugate of the first enzyme and some of the probes are bound to a conjugate of the second enzyme. The assay can be used to compare biological samples (e.g., mRNA populations from different cells) on the same support surface. Alternatively, one of the chemiluminescent signals generated can be used as a control signal for normalizing the chemiluminescent assay data.

    摘要: Probes labeled with 1,2-dioxetane precursors can be employed in a variety of assays. The probes may be nucleic acid, peptide nucleic acid, proteins including enzyme, antibody or antigen, steroid, carbohydrate, drug or non-drug hapten. The probe is provided with a 1,2-dioxetane precursor bound thereto, generally either covalently, or a strong ligand bond. The dioxetane precursor moiety is converted to a bound 1,2-dioxetane by exposure to singlet oxygen. These dioxetane (labels) either spontaneously decompose, or are induced to decompose by an appropriate trigger to release light. The trigger may be a change in pH temperature, or an agent which removes a protective group. Assay formats in which these 1,2-dioxetane labeled probes and referents may be used to include hybridization assays, immuno assays, gel-based assays and Capillary Zone Electrophoresis.
