Atezolizumab (MPDL3280A) is a selective humanized monoclonal IgG1 antibody against programmed death ligand 1 (PD-L1), used for cancer research.

Human IgG1 kappa

Human IgG1 kappa, Isotype Control

Humanized

Atezolizumab (0, 2.5, 5, 10, 20, and 40?μg/ml; 24 hours; HOS and 143B cells) inhibits proliferation and induces immune-independent apoptosis of osteosarcoma cells^[1].
Atezolizumab impairs the function of mitochondria to cause the imbalance between oxidants and antioxidants. Atezolizumab induces mitochondria-related apoptosis of osteosarcoma cells by activating JNK pathway^[1].
Atezolizumab (10 μg/ml; 24 hours; HOS and 143B cells) induces autophagy in osteosarcoma cells^[1].
