"Improved methods and novel compositions for enzyme complementation assays for qualitative and quantitative determination of a suspected analyte in a sample. The use of enzyme-acceptor and enzyme-donor polypeptides prepared by recombinant DNA techniques, DNA synthesis or chemical polypeptide synthesis techniques which are capable of interacting to form an active enzyme complex having catalytic activity characteristics of ß-galactosidase is described. Both homogeneous and heterogeneous assays utilizing these polypeptides are described.
"改进的酶互补测定方法和新型组合物,用于定性和定量测定样品中的可疑分析物。描述了通过重组 DNA 技术、DNA 合成或化学多肽合成技术制备的酶受体和酶供体多肽的使用方法,这些多肽能够相互作用形成具有ß-半乳糖苷酶催化活性特征的活性酶复合物。文中还描述了利用这些多肽进行的均相和异相检测。
