The efficiency of the transfection over time. Cell media when expressing different formats of antibodies 1 were sampled at several time points (2, 3, 6, 7, and 8 days post-transfection) and antibody concentration was measured by ELISA (left y-axis, n = 3 for day 6, 7, and 8 days post-transfection). Right axis is the cell viablity as measured in media samples obtained from several time points post-transfection (n = 5, error bars depict standard deviation)
