Figure 4. (A) Viability of dispersed primary mouse islet cells at 48 h: Ratio of viable to dead cells in dispersed primary mouse islets using the Multitox^® assay following exposure to 0.1 µmol/L CdCl2 for 8 or 48 h compared with control (n = 3, each in triplicate). (B) Representative blot of the expression of the heavy metal toxicity marker Heat Shock Protein 70 (HSP70) in dispersed primary mouse islets following exposure to 0.1 µmol/L CdCl2 for 48 h compared with non-exposed control cells.
