Evaluation of Biological Toxicity of CdTe Quantum Dots with Different Coating Reagents according to Protein Expression of Engineering Escherichia coli

Figure 3

The expression of the GST protein of engineering E. coli cells after treatment with different concentrations of MPA-CdTe QDs (a), GSH-CdTe QDs (b), and Cys-CdTe QDs (c). Lane 1: the control (untreated engineering E. coli cells). Lanes 2–7: engineering E. coli cells treated with CdTe QDs at a concentration range (left to right) of 5, 10, 50, 100, 200, and 500 nM.
