Cell density (circle-solid line) and viability (square-dashed line) profiles of HEK-293-E2-CD154 cell cultures with the four commercial media evaluated. a CDM4HEK293 culture media, b SFM4HEK293 culture media, c CPCHO culture media, d ProS293CDM. Each point represents the average from four determinations (two cell counts from two biological replicates). Error bars represent standard deviations
