    • PURPOSE: A recombinant Sabin type 1 poliovirus vector and a recombinant vaccine composition against poliovirus are provided, thereby inducing the formation of neutralizing antibodies against Sabin types 1, 2 and 3 polioviruses, and preventing the side-effects of OPV(attenuated oral polio vaccine; Sabin). CONSTITUTION: The recombinant Sabin type 1 poliovirus vector comprises (a) a genomic nucleotide sequence of Sabin type 1 poliovirus; (b) a nucleotide sequence encoding the additional poliovirus protease digesting site; and (c) nucleotide sequences encoding Sabin types 2 or 3 VP1 neutralizing epitopes, and connected to the nucleotide sequence encoding the additional poliovirus protease digesting site, wherein the protease is poliovirus 3C protease or poliovirus 2A protease; the nucleotide sequence encoding the Sabin type 2 VP1 neutralizing epitope is set forth in SEQ ID NO: 1; and the nucleotide sequence encoding the Sabin type 3 VP1 neutralizing epitope is set forth in SEQ ID NO: 2. The recombinant vaccine composition against poliovirus comprises (a) the recombinant Sabin type 1 poliovirus derived from the recombinant Sabin type 1 poliovirus vector; and (b) pharmaceutically acceptable carriers.
    • 目的:提供重组Sabin 1型脊髓灰质炎病毒载体和针对脊髓灰质炎病毒的重组疫苗组合物,从而诱导针对Sabin 1,2型和3型脊髓灰质炎病毒的中和抗体的形成,并防止OPV(减毒口服脊髓灰质炎疫苗; 萨宾)。 构成:重组Sabin 1型脊髓灰质炎病毒载体包含(a)Sabin 1型脊髓灰质炎病毒的基因组核苷酸序列; (b)编码另外的脊髓灰质炎病毒蛋白酶消化位点的核苷酸序列; 和(c)编码Sabin型2或3个VP1中和表位的核苷酸序列,并连接到编码另外的脊髓灰质炎病毒蛋白酶消化位点的核苷酸序列,其中该蛋白酶是脊髓灰质炎病毒3C蛋白酶或脊髓灰质炎病毒2A蛋白酶; 编码Sabin2型VP1中和表位的核苷酸序列如SEQ ID NO:1所示; 并且编码Sabin 3型VP1中和表位的核苷酸序列如SEQ ID NO:2所示。针对脊髓灰质炎病毒的重组疫苗组合物包含(a)源自重组Sabin 1型脊髓灰质炎病毒载体的重组Sabin 1型脊髓灰质炎病毒; 和(b)药学上可接受的载体。

    • PURPOSE: The monoclonal antibody 3-6-A which acts on the extracellular region of DM alpha protein was obtained. CONSTITUTION: The monoclonal antibody 3-6-A is manufactured by the following steps of: 1)preparing a recombinant plasmid pBlueBacHis2A-DMα by cloning DNA fragment of 609 bp, which codes extracellular region of DMα gene, into pBlueBacHis2A; 2)transfecting High-5 cell with plasmid pBlueBacHis2A-DMα and (full-length) DNA Bac-N-Blue to prepare recombinant Baculovirus; 3) obtaining cell extract by infecting High-5 cell with the recombinant Bac-N-Blue-DMα and purifying a recombinant DMα protein using Ni+-NTA column; 4) preparing a hybridoma cell, KHB-DM, which produces monoclonal antibody 3-6-A, by fusing splenocyte of BALB/c mouse and myelomaSp2/0; 5) obtaining monoclonal antibody 3-6-A by culturing the hybridoma cell KHB-DM.
    • 目的:获得作用于DMα蛋白细胞外区域的单克隆抗体3-6-A。 构成:通过以下步骤制造单克隆抗体3-6-A:1)通过将编码DMα基因的细胞外区的609bp的DNA片段克隆到pBlueBacHis2A中来制备重组质粒pBlueBacHis2A-DMα; 2)用质粒pBlueBacHis2A-DMα和(全长)DNA Bac-N-Blue转染高-5细胞,制备重组杆状病毒; 3)用重组Bac-N-Blue-DMα感染High-5细胞并用Ni + -NTA柱纯化​​重组DMα蛋白获得细胞提取物; 4)通过融合BALB / c小鼠和骨髓瘤SP2 / 0的脾细胞来制备产生单克隆抗体3-6-A的杂交瘤细胞KHB-DM; 5)通过培养杂交瘤细胞KHB-DM获得单克隆抗体3-6-A。
