Atezolizumab (trade name Tecentriq) is a fully humanized, engineered monoclonal antibody of IgG1 isotype against the protein programmed cell death-ligand 1 (PD-L1). In 2015, it was in clinical trials as an immunotherapy for several types of solid tumors. It was under investigation by Genetech/Roche. In April 2016, Roche announced that atezolizumab had been granted fast track status for lung cancer by the FDA. In May 2018, Tecentriq was in combination with Avastin and standard chemotherapy for some patients with lunch cancer was granted priority review.

SEC-HPLC detection for Research Grade Cosibelimab.　　|　Detects CD274/PD-L1/B7-H1 in indirect ELISAs.　　|　SDS-PAGE for Research Grade Cosibelimab.　　|　Flow-cytometry using APC anti-human CD274 antibody. MDA-MB-231 cells were stained with an irrelevant antibody (Blue Histogram) or an APC anti-human CD274 monoclonal antibody (Catalog: HV974066, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer. ### Flow-cytometry using FITC anti-human CD274 antibody. MDA-MB-231 cells were stained with an irrelevant antibody (Blue Histogram) or an FITC anti-human CD274 monoclonal antibody (Catalog: HV974066, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer. ### Flow-cytometry using PE anti-human CD274 antibody. MDA-MB-231 cells were stained with an irrelevant antibody (Blue Histogram) or an PE anti-human CD274 monoclonal antibody (Catalog: HV974066, Yellow Histogram) at a concentration of 5 µg/ml for 30 mins at RT. After washing, cells analysed on a NovoCyte Flow Cytometer. ### Flow-cytometry using anti-human CD274 antibody. Untransfected cells (blue Histogram) and Transfected cells (Yellow Histogram) were stained with an anti-human CD274 monoclonal antibody (Catalog: HV974066) at a concentration of 5 µg/ml for 30 mins at RT. After washing, bound antibody was detected using a Goat Anti-Human IgG H&L Polyclonal Antibody, FITC (abinScience: HF690414) and cells analysed on a NovoCyte Flow Cytometer.
