The metabolic activity curve of cells.
The cell survival curve by MTT assay for three cell lines in its respective culture medium at different time points. The longitudinal axis Y displays the cell OD value of MTT, which refers to overall cell survival. Data are shown as the Mean ± SD (n = 4). *P < 0.05 significant difference with respect to control medium values; **P < 0.01 significant difference with respect to control medium values. A. CHO cells; B. MARC-145 cells; C. HeLa cells.
