ABSTRACT
Bi-specific antibodies (BsAb) P210/MMC, P210/TNP and P40/CD3 were prepared with different approaches. Among 11 fusions, 7, 484 wells were planted, and 223 dual positive wells were obtained from 1, 111 growth wells, only five hybrid-hybridomas secreting BsAb were obtained, showing the difficulties to prepare BsAb. It was shown that bridge assay is very important for identification of the BsAb. Among 12 triomas secreting y and ? chains, only two had BsAb. Therefore, the frequency for y and ? to combine to BsAb was 16.7(2/12). BsAb(P210/TNP) with versatile adaptor could mediate cytotoxic effects on target cells of different cytotoxic agents conjugated with TNP.Moreover, BsAb(P40/CD3) could mediate cytotoxic effects of peripheral blood lymphocytes (PBLs) on target cells. With local injection, four times treatments could abolish the tumor xenografts in nude mice.
