Rats (Control = 3, BCNU = 3) were perfused intracardially with 4% paraformaldehyde (PFA; Sigma-Aldrich). Then, the brains were removed and placed in a fresh 4% solution overnight. Next, they were transferred to a 20% sucrose (w/v) solution in PBS 1x (w/v) for 24 h, followed by a 30% sucrose (w/v) solution with the same duration. Tissues were frozen using absolute ethanol and liquid nitrogen and stored at − 20 °C until sectioning. Coronal slices (20 μm thick) were obtained with a cryostat microtome (Leica) near Bregma (9.20 mm). Sections were preserved in PBS 1x (w/v), then washed (5 × 10 min) with PBS 1x + Tween 20, 0.3% (w/v) (Sigma-Aldrich). Blocking was performed with PBS 1x, Triton X-100, and 0.3% (v/v) BSA 2% (blocking solution) for 45 min at room temperature, then incubated overnight at 4 °C with primary layer-specific antibodies (NBP1-86671, Foxp2; polyclonal 1:2000, NBP1-84004, Necab; polyclonal 1:500, Novus Biologicals) and ab104224 NeuN 1:350 (Abcam) and G3893, GFAP 1:350 (Sigma-Aldrich).

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.
