Figure 1. ELISA plate pre-coated by 2 μg/mL (100 μL/well) Human PD-L1 Protein, mFc-His tag(PME100023) can bind Anti-PD-L1 (SGNPDL 1V biosimilar) mAb (BME100287)in a linear range of 1.6-8.0ng/mL.

Figure 2. Flow cytometry analysis with 0.5μg/ml Anti-PD-L1(SGNPDL 1V biosimilar) mAb (BME100287) on HEK293 cells transfected with human PD-L1 (Blue histogram) or HEK293 transfected with irrelevant protein (Red histogram).

Figure 3. FACS analysis showed that the binding of Biotin-PD-1 to K562 cells overexpressing PD-L1 was inhibited by increasing concentrations of neutralizing anti-PD-L1 antibodies. The concentration of Biotin-PD-1 used was 1.5 μg/mL. BME100288 and BME100287 exhibited dose-dependent blocking activity, while the irrelevant control antibody showed no inhibition.

「神药」再显威!杨黄浩等让二甲双胍扮演 PD-L1 「单抗」角色,提高治疗效果
以 PD-1/PD-L1 为代表的免疫检查点抑制剂(Immune Checkpoint Blockades, ICBs)在实体瘤中「大杀四方」,取得了传统治疗方法未有的良好疗效,逐渐成为了继手术、放疗、化疗、靶向治疗后又一种重要的肿瘤治疗手段。然而,免疫检查点抑制剂在实体瘤中的总体有效率依然仅有 20-30%。目前的 PD-1/PD-L1 等抗体类药物治疗依然存在着一些不可避免的问题, 如致命的免疫相关不良事件 (irAE)、复杂的生产工艺、高昂的成本等。此外,基于抗体的 ICBs 通过构象
