Impact of Cadmium on Intracellular Zinc Levels in HepG2 Cells: Quantitative Evaluations and Molecular Effects

Figure 2

Spectrofluorimetric quantification of intracellular labile zinc. Samples are expressed as Δ% ± SD versus controls (cells grown in control medium in the presence of 25 μM Zinquin). significantly different (Student’s -test) from the corresponding Cd or Zn treatment at lower concentration.
