为了治疗白血病和恶性淋巴瘤患者的微小残留病,我们构建了特异性针对B细胞上的人CD 19和T细胞受体复合物的CD 3 β链的异源二聚体双抗体。使用含有双顺反子操纵子的载体在大肠杆菌中表达双特异性双抗体,用于共分泌VH 3-VL 19和VH 19-VL 3单链抗体片段(scFv)。通过固定化金属亲和层析(IMAC)从周质提取物和培养基中一步纯化。流式细胞术实验揭示了双抗体与CD 3和CD 19阳性细胞的特异性相互作用,其结合亲和力接近亲本scFv的亲和力。当在37°C下在人血清中孵育时,其稳定性低于抗CD 3 scFv,但比抗CD 19 scFv更稳定。在细胞毒性试验中,双抗体被证明是一种有效的试剂,用于重新靶向外周血淋巴细胞以裂解表达CD 19抗原的肿瘤细胞。细胞裂解的效率相比,有利地与获得的双特异性抗体(BsAb)的相同的双特异性,制备的quadroma技术。Int.

For the treatment of minimal residual disease in patients with leukemias and malignant lymphomas, we constructed a heterodimeric diabody specific for human CD19 on B cells and CD3ϵ chain of the T cell receptor complex. The bispecific diabody was expressed in Escherichia coli using a vector containing a dicistronic operon for co‐secretion of VH3‐VL19 and VH19‐VL3 single‐chain Fv fragments (scFv). It was purified in one step by immobilized metal affinity chromatography (IMAC) from the periplasmic extract and culture medium. Flow cytometry experiments revealed specific interactions of the diabody with both CD3 and CD19 positive cells, to which it bound with affinities close to those of the parental scFvs. It was less stable than anti‐CD3 scFv but more stable than anti‐CD19 scFv when incubated in human serum at 37°C. In cytotoxicity tests, the diabody proved to be a potent agent for retargeting peripheral blood lymphocytes to lyse tumor cells expressing the CD19 antigen. The efficiency of cell lysis compared favorably with that obtained with a bispecific antibody (BsAb) of the same dual specificity that was prepared by the quadroma technique. Int. J.
