摘要
抗肿瘤新药表阿霉素(EPI)通过葡聚糖T10与抗人B淋巴细胞白血病单抗(B159)连接制备免疫结合物。该结合物保持了原有的抗体活性,在体外对人B淋巴母细胞Raji显示出特异的杀伤作用,并具有良好的稳定性。
The antiumor drug Epirubicin(EPI) was conjugated with the anti-human B lymphocytic leukemia monoclonal antibody(B159) via dextran T10. The conjugate retained full antibody binding activity as determined by the living cell fluoroimmunoassay, and exhibited highly selective cytotoxicity on human B lymphoblast Raji in vitro. No free EPI released from the conjugate was detected after it was stored at 4℃ for 120 days as measured by chromatography on a Sephadex G150 column.
