    • PURPOSE: A method for manufacturing bispecific antibody of a two-in-one type is provided to select phage which is able to recognize two different antigens. CONSTITUTION: A method for manufacturing bispecific antibody of a two-in-one type comprises: a step of selectively enriching a phage group having a specific antibody fragment and collecting the phages; a step of infecting the phage to a host cell to prepare a plasmid; a step of removing DNA fragment of light chain from the plasmid and inserting a light chain library to prepare a light chain shuffling library; and a step of panning the light chain shuffling library with a second target antigen. The host cell is E. coli.
    • 目的:提供一种制备二合一双型特异性抗体的方法,以选择能识别两种不同抗原的噬菌体。 构成:二合一双型特异性抗体的制备方法包括:选择性富集具有特异性抗体片段的噬菌体组并收集噬菌体的步骤; 将噬菌体感染宿主细胞以制备质粒的步骤; 从质粒中除去轻链DNA片段并插入轻链文库以制备轻链洗牌文件库的步骤; 以及用第二靶抗原平移轻链改组文库的步骤。 宿主细胞是大肠杆菌。

    • PURPOSE: A myostatin inhibitor including a DLK1 extracellular water-soluble domain as an active ingredient is provided to prevent and treat a disease that needs muscular cell differentiation including muscle microsomia or metabolic diseases by hindering mechanism of myostatin as the inhibitor binds to the myostatin or activin receptor type 2B. CONSTITUTION: A composition for myostatin activity inhibition comprises adelta-like 1 homolog (DLK1) extracellular water-soluble domain, a fraction of a DLK1 extracellular water-soluble domain, or a mutant or a fraction of the mutant of a DLK1 extracellular water-soluble domain as an active ingredient. The DLK1 extracellular water-soluble domain has an amino acid sequence represented by SEQ ID No. 29. The composition for myostatin activity inhibition comprises a DLK1 extracellular water-soluble domain or a fraction thereof, and a DLK1-Fc fused protein to which a human antibody Fc region is fused as an active ingredient. A pharmaceutical composition for preventing or treating a myostatin-related disease comprises a DLK1 extracellular water-soluble domain, a fraction of a DLK1 extracellular water-soluble domain, or a mutant of a DLK1 extracellular water-soluble domain or a fraction of the mutant as an active ingredient.
