| Bioactivity | Iscalimab (CFZ-533) is a non-depleting IGg1 monoclonal antibody targeting CD40 (KD: 0.3 nM). Iscalimab can be used for research of Graves' hyperthyroidism and autoimmune diseases[1][2][3]. |
| Invitro | Iscalimab (0.01-1 μg/mL，过夜) 抑制 rCD154 诱导的原代单核细胞衍生树突状细胞 (moDC) 产生 TNF，IC50 为 0.04 μg/mL[3]。Iscalimab (3 天) 抑制 rCD154 诱导的人、恒河猴和食蟹猴 PBMC 增殖，IC50 分别为 0.02、0.03 和 0.01 μg/mL[3]。Iscalimab 结合来自人、恒河猴和食蟹猴的 B 细胞上的 CD40，EC50 值约为 0.2 μg/mL[3]。Iscalimab (2 μg/mL, 3 h) 以 CD40 依赖性方式被 B 细胞内化[3]。 Cell Viability Assay[3] Cell Line: |
| In Vivo | Iscalimab (150 mg/kg/周，皮下注射，持续 13 周) 耐受性良好，不会对恒河猴造成任何剂量限制性毒性[3]。Iscalimab (10 mg/kg，静脉注射) 完全抑制恒河猴的 T 细胞依赖性抗体反应[3]。Iscalimab (30 mg/kg，静脉内) 可延长肾移植食蟹猴的同种异体移植物存活期[4]。 Animal Model: |
