The secondary antibody (donkey anti-rabbit Cy3, donkey anti-rabbit Cy2, donkey anti-mouse Cy2; 1:200; Jackson Lab) was added with the nuclear stain DAPI (1:1000; Sigma-Aldrich) and incubated at room temperature for approximately 1 h, followed by 2–3 rinses with KPBS. The immunocytochemically labelled cells were then visualized with a Leica microscope (model DMI6000 B), and images were cropped and adjusted in Adobe Photoshop CC 2015.

Quantifying pMeCP2 and Fos in Brain

Check if the same lab product or an alternative is used in the 5 most similar protocols
Brains were cut to 40µm coronal sections on a freezing microtome, and brain regions (prelimbic and infralimbic regions of the medial prefrontal cortex, nucleus accumbens, and basolateral amygdala) were identified by anatomical landmarks. Sections were blocked in 10% normal goat serum with 0.3% Triton X-100 in PBS and were incubated overnight in primary antibodies, which included rabbit anti-phospho-Ser421 MeCP2 (1:15,000; (Deng et al. 2010 (link))) and rabbit anti-Fos (1:10,000; Ab-5; Millipore). Because both antibodies were raised in rabbit, sections could not be co-stained for both pMeCP2-S421 and Fos; thus we used adjacent sections from each animal for these analyses. Sections were visualized by application of donkey anti-rabbit Cy3 or donkey anti-rabbit Cy2 (1:500; Jackson ImmunoResearch) secondary antibodies. Hoechst dye was added to visualize nuclei and the sections were mounted in Vectashield (Vector Laboratories). To minimize bleaching, sections were stored at all stages in dark conditions and were exposed for the minimum duration of time to bright field illumination.

After the electrophysiological experiments, mice were transcardially perfused with 4% paraformaldehyde (PFA) under deep isoflurane anesthesia to characterize the opsin expression. Brains were removed, fixed overnight in 4% PFA, and transferred to 30% sucrose solution. Coronal brain sections of 70 μm thickness were prepared using a vibratome (Leica, Wetzlar, Germany). For permeabilization, slices were incubated with 0.1% Triton X-100 and 5% normal donkey serum (Invitrogen, Life Technologies, Carlsbad, CA) in phosphate buffer solution for 90 min. Slices were incubated with goat anti-PV (1:200, Swant, Marly, Switzerland) or rabbit anti-CamKII (1:200, Epitomics, Burlingame, CA) at 4 °C overnight. On the next day, slices were incubated with the secondary antibodies Cy-2 donkey anti-goat (1:200, Jackson Immuno Research, West Grove, PA), or Cy-2 donkey anti-rabbit (1:200, Jackson Immuno Research, West Grove, PA), and a fluorescent Nissl stain (red 615 nm, Neurotrace, Molecular Probes, Life Technologies, Carlsbad, CA). Slices were mounted using antiquenching Vectashield (Vector Laboratories, Burlingame, CA).

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.
