Hemophilia B is a congenital bleeding disorder caused by factor IX (FIX) deficiency. Generation of recombinant FIX (rFIX) is required for detecting a Hemophilia B indicator, anti-FIX antibody. In this study, we described a method for producing recombinant FIX (rFIX) using . We constructed a FIX-expressing plasmid without a fusion tag protein-encoding gene and produced rFIX as a soluble form within five days. Dose-dependent curve was obtained from ELISA using anti-FIX antibody, indicating that the rFIX can be used as an antigen to detect anti-FIX antibody with high affinity and sensitivity.
血友病B是一种由FIX缺乏引起的先天性出血性疾病。检测血友病B指标抗FIX抗体需要生成重组FIX(rFIX)。在本研究中,我们描述了一种使用[具体方式未给出]生产重组FIX(rFIX)的方法。我们构建了一个不含融合标签蛋白编码基因的FIX表达质粒,并在五天内以可溶形式生产出rFIX。使用抗FIX抗体通过ELISA获得了剂量依赖曲线,表明rFIX可用作抗原以高亲和力和灵敏度检测抗FIX抗体。
