    • PURPOSE: A recombinant protein useful for the detection of tsutsugamushi infection, a gene encoding the same, and a diagnostic kit using the same are provided, which recombinant protein has high antigenicity, and is easily cloned into an expression vector and easily cultured, so that the recombinant protein can be mass-produced. CONSTITUTION: The recombinant protein or a mutant which has the surface antigen activity of Orientia tsutsugamushi Pajoo and has the amino acid sequence of SEQ ID NO:1 or has 90% homology to the amino acid sequence of SEQ ID NO:1 is provided. A gene encoding the recombinant protein or mutant has the nucleotide sequence of SEQ ID NO:2. An expression vector p56kDa contains the gene of SEQ ID NO:2. A transformed host cell, Escherichia coli NIH/BL/56kDa-ET15B(KCCM 10489) is produced by transforming the host cell with the expression vector p56kDa. The method for producing the recombinant protein or mutant comprises culturing the Escherichia coli NIH/BL/56kDa-ET15B(KCCM 10489) and separating the recombinant protein or mutant from the cultured medium.
    • 目的:提供可用于检测恙虫病感染的重组蛋白,编码恙虫病感染的基因,以及使用该重组蛋白的诊断试剂盒,该重组蛋白具有高抗原性,易于克隆到表达载体中并容易培养,使得 可以大量生产重组蛋白。 构成:提供了具有东方恙虫Pajoo的表面抗原活性并具有SEQ ID NO:1的氨基酸序列或与SEQ ID NO:1的氨基酸序列具有90%同源性的重组蛋白或突变体。 编码重组蛋白或突变体的基因具有SEQ ID NO:2的核苷酸序列。 表达载体p56kDa含有SEQ ID NO:2的基因。 通过用表达载体p56kDa转化宿主细胞产生转化的宿主细胞大肠杆菌NIH / BL / 56kDa-ET15B(KCCM 10489)。 重组蛋白质或突变体的制备方法包括培养大肠杆菌NIH / BL / 56kDa-ET15B(KCCM 10489),并从培养基中分离重组蛋白质或突变体。
