Normalized CTCF values plotted against pH. The Y-axis represents fluorescent intensities in CTCF, while the X-axis represents pH values ranging from 2 to 12. Error bars indicate the mean standard deviation derived from three independent biological treatments. The cells were treated with 2.0 ppb of Cd²⁺, Zn²⁺, Pb²⁺, and Ni²⁺. The cells were grown at a constant temperature of 37 °C. Plots for Cd²⁺, Zn²⁺, Pb²⁺, and Ni²⁺ are depicted in blue, orange, ash and yellow, respectively, in the specified order
