Expression of luciferase gene in different concentrations of zinc, tin and cadmium. Heavy metal had no effect on the stimulation of the pbr promoter. The pbr promoter is specific to lead, and other heavy metals such as a zinc (Zn), b tin (Sn) a and c cadmium (Cd), do not activate the promoter and significant expression of a reporter gene
