    • A vector for expressing antibody fragments and a method for producing recombinant phage that displays the antibody fragments by using the vector are provided to obtain a combinatorial Fab antibody library easily without the contamination of a helper phage. A method for manufacturing pHf1g3T-1 phagemid comprises the steps of (i) enzymatically decomposing pBR322 plasmid into Pst I and EcoR I to produce a DNA fragment; (ii) performing PCR reaction of pCMTG-SP112 plasmid by using a primer set consisting of SEQ ID NO:1 and SEQ ID NO:2 and enzymatically decomposing the PCR product into Pst I and Mun I to produce a DNA fragment; (iii) ligating the DNA fragment of the step (i) and the DNA fragment of the step (ii); (iv) transforming a cell for TG1 transformation by using the DNA ligated in the step (iii); and (v) cultivating the TG1 cell transformed in the step (iv) and separating and purifying the phagemid from the culture material.
    • 提供用于表达抗体片段的载体和通过使用载体产生显示抗体片段的重组噬菌体的方法,以便容易地获得组合Fab抗体文库,而不会引起辅助噬菌体的污染。 制备pHf1g3T-1噬菌粒的方法包括以下步骤:(i)将pBR322质粒酶促分解成Pst I和EcoRI以产生DNA片段; (ii)通过使用由SEQ ID NO:1和SEQ ID NO:2组成的引物组进行pCMTG-SP112质粒的PCR反应,并将PCR产物酶促分解成Pst I和Mun I以产生DNA片段; (iii)连接步骤(i)的DNA片段和步骤(ii)的DNA片段; (iv)通过使用步骤(iii)中连接的DNA转化TG1转化的细胞; (v)培养在步骤(iv)中转化的TG1细胞,并从培养物质中分离和纯化噬菌粒。
