    • The present invention is related generally to methods and compositions for identifying and quantitating particular .alpha.1-antichymotrypsin species in a biological sample. More particularly, the present invention is related to methods and compositions for detecting and measuring a brain .alpha.1-antichymotrypsin species that is produced in brain tissue of individuals having a neuropathological condition and which is detectable in accessible biological samples. The invention provides detection assays, such as sandwich binding assays, for detecting and quantitating brain .alpha.1-antichymotrypsin in a biological sample, such as blood, urine, cerebrospinal fluid, or tissue. These detection assays are useful for detecting and diagnosing neuropathological diseases and for identifying cells of a human central nervous system lineage, and for other medical applications. The invention also provides binding components, such as antibodies that bind to brain .alpha.1-antichymotrypsin, and which have potential therapeutic and diagnostic medical imaging applications.
    • 本发明一般涉及鉴定和定量生物样品中特定α1-抗胰凝乳蛋白酶物质的方法和组合物。 更具体地说,本发明涉及用于检测和测量在具有神经病理学病症的个体的脑组织中产生并且在可及生物样品中可检测的脑α1-抗胰凝乳蛋白酶物质的方法和组合物。 本发明提供了用于检测和定量生物样品例如血液,尿液,脑脊髓液或组织中的脑α1-抗胰凝乳蛋白酶的检测测定法,例如夹心结合测定法。 这些检测测定法可用于检测和诊断神经病理学疾病和用于鉴定人类中枢神经系谱系的细胞和其它医学应用。 本发明还提供结合组分,例如结合脑α1-抗胰凝乳蛋白酶的抗体,并具有潜在的治疗和诊断医学成像应用。
