    • Disclosed are fusion proteins comprising two detection portions and a periplasmic binding protein (PBP) portion between this two detection portions which undergoes a conformational change upon binding of a compound. Also described are nucleic acid molecules comprising a nucleotide sequence encoding such a fusion protein as well as expression cassettes, vectors, transgenic plants and transgenic non-human animals comprising said nucleic acid molecules. In addition, described are methods for detecting an analyte in a sample or in a cell using said fusion protein, and optionally, a control sensor allowing a calibration of analyte detection made by said fusion protein. Also described are such control sensors and nucleic acid molecules encoding them, as well as diagnostic compositions, kits and uses of the fusion protein and the control sensor for in vitro or in vivo analyte detection and preparing a diagnostic composition.
    • 公开了包含两个检测部分和这两个检测部分之间的周质结合蛋白(PBP)部分的融合蛋白,其在结合化合物后发生构象变化。 还描述了包含编码这种融合蛋白的核苷酸序列的核酸分子以及包含所述核酸分子的表达盒,载体,转基因植物和转基因非人动物。 另外,描述了使用所述融合蛋白检测样品或细胞中分析物的方法,以及任选地允许校准由所述融合蛋白产生的分析物检测的对照传感器。 还描述了这样的对照传感器和编码它们的核酸分子,以及用于体外或体内分析物检测和制备诊断组合物的融合蛋白和对照传感器的诊断组合物,试剂盒和用途。
