Figure 3. Pb2+ exposure increases the levels of NR2B-containing receptors.

Figure 3

[3H]-ifenprodil radioligand binding assays revealed a ~30% increase in specific binding after exposure to 1 μM Pb2+. Assays were performed in the presence of GBR to prevent binding of radioligand to sigma receptors. Data are shown as the mean ± SEM and are the result of 3 independent assays. * = significance from all other treatments (Fisher’s Protected LSD).
