Atezolizumab 是一种人源化单克隆抗体 IgG1，能抵抗程序性死亡因子配体1 ，可用于癌症研究。

Atezolizumab anti-PD-L1) is a fully humanized IgG1 monoclonal antibody that blocks the interaction of PD-L1 with both PD-1 and B7.1 but not the interaction of PD-L2 with PD-1.

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.
