After completion of the behavioral experiment and blood collection, the mice were euthanized and their brain tissues were surgically removed, dissected, and preserved in normal saline. For the analytical determination of Pb, a 10% homogenate of the brain was prepared in Tris-HCl (50 mM). The homogenates were re-centrifuged at 17,000 rpm at 4 °C for 5 min and supernatants were filtered using 0.45 μm pore filters and analyzed by ICP–MS (Inductively Coupled Plasma Mass Spectrometer): ELAN 9000 (Perkin Elmer SciexInstrumento, Concord, Ontario, Canada). Nitric acid (69% v/v), super purity grade was supplied from Romil, Cambridge, UK. Hydrochloric acid (37% v/v) and hydrofluoric acid (40% v/v) were supplied by Merck (Darmstadt, Germany). High purity water obtained from the Millipore Milli-Q water purification system was used throughout the work. The ICP–MS calibration was carried out by external calibration with the blank solution and three working standard solutions (20, 40, and 60 ppm), starting from 1000 mg/L single standard solutions for ICP–MS (A ristar grade, BDH Laboratory Supplies, Poole, UK, for Cd).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
