Figure 2: Expression level of the apoptotic-related proteins in HeLa cells determined by Western Blot analysis. β-actin acts as a loading control. Protein bands were quantified by densitometric analysis. Relative expression was calculated by the optical density ratio of protein to β-actin and normalized against the control.
