    • 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.
    • 用1,2-二氧杂环丁烷前体标记的探针可用于多种测定。 探针可以是核酸,肽核酸,蛋白质,包括酶,抗体或抗原,类固醇,碳水化合物,药物或非药物半抗原。 探针具有与其结合的1,2-二氧杂环丁烷前体,通常共价或强配体键。 通过暴露于单线态氧将二氧杂环丁烷前体部分转化为结合的1,2-二氧环乙烷。 这些二氧杂环丁烷(标记)会自发分解,或被适当的触发剂诱导分解以释放光。 触发可能是pH温度的变化,或者是除去保护基团的试剂。 这些1,2-二氧杂环丁烷标记的探针和指示物可用于包括杂交测定,免疫测定,基于凝胶的测定和毛细管区域电泳的测定形式。

    • 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.
    • 具有烷氧基取代基的双金刚烷基二氧杂环丁烷和二氧杂环丁烷环上苯基或萘基的芳族取代基可以被活化成化学发光,如果芳族取代基具有指定为OX的部分,其中X被允许二氧杂环丁烷的酶切割 在与接触。 化学发光反应的T + E,1/2 + EE动力学以及化学发光反应的信号强度或量子产率可以通过选择吸电子基团或给电子基团Z来改变, 在芳族取代基上除了与二氧杂环丁烷的连接点相邻的位置之外的位置。 信号强度可以通过认可的化学发光增强剂进一步增强。
