Normalized CTCF values plotted against incubation temperature. The Y-axis represents fluorescent intensities in CTCF, while the X-axis represents incubation temperature in °C. Error bars indicate the 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 pH of 7.0. Plots for Cd²⁺, Zn²⁺, Pb²⁺, and Ni²⁺ are depicted in blue, ash, orange, and yellow, respectively, in the specified order
