    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.

    摘要: A new class of stable dioxetanes bears a polycyclic stabilizing group and aryloxy moiety, the oxygen atom of which is provided with a protective group which can be removed by an enzymatic or chemical trigger admixed with the dioxetane. The polycyclic stabilizing group is preferably spiroadamantane. The group further bears an alkoxy, aryloxy, aralkyloxy or cycloalkyloxymoiety which is partially or completely substituted with halogens, particularly fluorine and chlorine. Proper selection of electron active groups on the stabilizing moiety, the aryl group and the OR group yields enhanced enzyme kinetics, superior light intensity and excellent detection sensitivity in various assays.

    摘要: Spiroadamantyl dioxetanes bearing an alkoxy substituent, and an aromatic substituent of phenyl or naphthyl on the dioxetane ring can be activated to chemiluminesce if the aromatic substituent bears a moiety designated OX, wherein the X is cleaved by an enzyme with which the dioxetane is permitted to come in contact with. The T.sub.1/2 kinetics of the chemiluminescent reaction, as well as the signal intensity, or quantum yield of the chemiluminescent reaction, can be altered by selection of an electron-withdrawing or an electron-donating group Z, at positions on the aromatic substituent other than those adjacent the point of attachment to the dioxetane. Signal strength can further be enhanced by recognized chemiluminescent enhancers.
