OCI-Ly8 was transduced to express green click beetle luciferase and ZsGreen using pHIV-Luc-ZsGreen (a gift from Bryan Welm [Addgene plasmid no. 39196]). These cells were cultured with healthy donor T cells (E:T ratio of 5:1) and different concentrations of mosunetuzumab (Genentech and Roche): 0, 1, 10, and 100 ng/ml. After 24 hours, cancer cell survival was monitored by luciferase bioluminescence using a BioTek Synergy H4 Imager (560 nm). Cell viability (%) was calculated relative to that of the Ctrl cancer cells and T cells without mosunetuzumab.
