| 产品描述 | Atezolizumab is an antibody inhibitor, a humanized monoclonal antibody, IgG1, which targets PD-L1 and blocks the interaction of PD-L1 with PD-1. Atezolizumab has antitumor activity and promotes T-cells to attack tumor cells. |
| 体外活性 | 方法:MDA-MB-231、BT-20、MDA-MB-468 细胞和 T 细胞共培养,用 Atezolizumab (50-100 µg/mL) 处理 4-24 h,进行 T cell-mediated cytotoxicity assay。 |
| 体内活性 | 方法:为检测体内抗肿瘤活性,将 Atezolizumab (10 mg/kg) 和 Bevacizumab (5 mg/kg) 腹腔注射给携带 A2780cis 异种移植物的 BALB/C nude 小鼠,每两天一次,持续三周。 |
| 细胞实验 | Objective: Determine the binding of [111In]PD-L1-mAb to tumor cell lines. Cells: NCI-H2444(Lung Cancer cell line), MDAMB231(Breast Cancer cell line),etc. Concentrations: 1 μCi/100μl. Incubation Time: 1 h. Method: Incubating 1 μCi of [111In]PD-L1-mAb with 1×106cells (in triplicate for each cell line) for 1h at 37°C. PD-L1 blocking was performed by adding a 10-fold molar equivalent excess of the non-labeled mAb. After incubation, cells were washed three times with cold PBS prior to counting on an automated gamma counter. |

案例一:将分离的CD8+T细胞与经Atezolizumab处理24小时的LoVo或HT29细胞共培养。通过乳酸脱氢酶(LDH)测定法评估CD8+T细胞对结直肠癌细胞的细胞毒性。结果发现,Atezolizumab增强了CD8T+细胞对LoVo和HT29细胞的细胞毒性。

案例二:将AMM16细胞分别转染siRNA ctrl(对照组)或siRNA AR(AR敲低组)。转染后,将细胞用不同浓度Atezolizumab(0、5、10、35 μg/mL)处理。通过乳酸脱氢酶(LDH)释放实验检测细胞毒性,发现AR 敲低能增强 Atezolizumab的细胞毒作用。
