The new human antibodies equipped with the human germ cell line VH3 and Vλ gene structures are provided with that a single strain antibody obtained from them individually or as combined, can bind specifically with a gene recombinant soluble human CD152(CTLA-4) antigen and also can react with an activated peripheral human T-cell elevating the expression of the CD152. ヒト胚細胞系VH3とVλ遺伝子構造を具えた新規ヒト抗体であって、それが個別で、或いは組み合わされてなる単株抗体が遺伝子組換えの可溶性ヒトCD152(CTLA−4)抗原と特異的に結合可能で、また、CD152表現を上昇する活性化周辺ヒトT細部との反応が可能である。 - 特許庁
