生物活性

TPP-9476 is an anti-human IL3RA (CD123) monoclonal antibody with human IL3RA Kd of 11 nM and cynomolgus monkey IL3RA Kd of 16 nM. TPP-9476 binds specifically to human and cynomolgus monkey IL3RA, undergoes target-dependent internalization into lysosomes of IL3RA-positive cells.TPP-9476 exerts antiproliferative effects in IL3RA-expressing acute myeloid leukemia and classical Hodgkin lymphoma cells, reduces tumor burden, improves survival, and induces complete tumor remission in relevant xenograft mouse models[1].

TPP-9476 (靶向 IL3RA 的抗体) (titrated log M values) 以高亲和力结合重组人及食蟹猴 IL3RA 蛋白,且可与 IL3RA 阳性的人急性髓系白血病细胞系 MV-4-11、MOLM-13 和 KG-1 发生特异性的、剂量依赖性结合,而不结合小鼠 IL3RA[1]
TPP-9476 (靶向 IL3RA 的抗体) (10-20 μg/mL; 0-6 h) 可被 IL3RA 阳性的 MOLM-13 和 MV-4-11 急性髓系白血病细胞特异性、时间依赖性地内吞,并且在 MOLM-13 细胞中与溶酶体共定位,但在 IL3RA 阴性的 HBL-1 细胞中无此现象[1]
TPP-9476 (靶向 IL3RA 的抗体) (up to 3.00 × 10-7 M; 72 h) 单独使用时,在 IL3RA 阳性的人急性髓系白血病和霍奇金淋巴瘤细胞系中无抗增殖活性,即使在孵育 72 h 后浓度高达 3.00 × 10-7 M 时也是如此[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
