ELISA binding of Anti-Atezolizumab monoclonal antibody, clone 55D8 (Cat # MAB23079) with Atezolizumab. While the antibody does not recognize the human IgG Fc fragment (data not shown). Coating antigen: Atezolizumab, 1 ug/mL. Anti-Atezolizumab monoclonal antibody, clone 55D8 (Cat # MAB23079) dilutions start from 1000 ng/mL. EC50 = 2.446 ng/mL.
Sandwich ELISA
Standard curve of Atezolizumab Sandwich ELISA. The Atezolizumab Sandwich ELISA assay is developed by using Anti-Atezolizumab monoclonal antibody, clone 55D8 (Cat # MAB23079) and Anti-Atezolizumab monoclonal antibody, clone 43H11 (Cat # MAB23080) as the capture and detection antibodies, respectively.
