Cells were washed in ice-cold PBS and total protein extracted in radioimmune precipitation assay (RIPA) buffer (25 mM Tris-HCl, pH7.6, 150 mM NaCl, 1% Nonidet P-40, 1% sodium deoxycholate, and 0.1% SDS). Equivalent protein mass was loaded on SDS-PAGE and transferred to Hybond ECL (GE HealthCare) nitrocellulose membrane. Antibodies MECP2 (Rabbit Anti-MECP2, 1:1000 dilution, Millipore, Cat# 07-013; RRID:AB_2144004), and Beta Actin (Mouse Anti-bActin, 1:5000 dilution, Sigma-Aldrich, Cat# A5441; RRID:AB_476744) were used. Near-Infra Red-conjugated secondary antibodies (IRDye 800CW Donkey anti-Mouse IgG, Cat# 926-32212, and IRDye 680RD Donkey anti-Rabbit IgG, Cat# 926-68073, 1:25000 dilution for both, LI-COR) were used and membranes scanned using LI-COR Odyssey CLx scanner according to manufacturer’s instructions. Acquired images were analyzed using ImageStudio v5.2.5.

Proteins (50 μg) were electrophoretically separated using a 4–20% SDS polyacrylamide gel and then transferred onto a nitrocellulose membrane (Bio-Rad). Membranes were blocked with Odyssey blocking buffer (LiCor) for 1 h at room temperature. Membranes were probed with the following primary antibodies: rabbit anti-MeCP2 (1:1000, Millipore 07–013), rabbit anti-mGlu7 antibody (1:1000, Millipore 07–239), mouse anti-Gapdh antibody (1:5000, ThermoFisher MA5-15738), and mouse anti-Tubulin antibody (1:500, Abcam ab44928) overnight at 4 °C. Membranes were washed three times with Tris-buffered saline and Tween 20 (TBS-T, 25 mM Tris, 150 mM NaCl, 0.05% Tween 20) and then incubated with either a goat anti-rabbit fluorescent secondary antibody (800, 1:5000, LiCor) or a goat anti-mouse fluorescent secondary antibody (680, 1:5000, LiCor). Fluorescence was then quantified using Image Studio Light software. Each value for MeCP2 and mGlu7 protein expression was first normalized to the value calculated for Gapdh expression (total protein blots) or Tubulin expression (synaptosome blots).

As previously described in Reference 33 (link), 50 μg of total protein was electrophoretically separated using a 4%–20% SDS polyacrylamide gel and transferred onto a nitrocellulose membrane (Bio‐Rad, Hercules, CA, USA). Membranes were blocked in Odyssey blocking buffer (LI‐COR, Lincoln, NE, USA) for 1 h at room temperature. Membranes were probed with primary antibodies overnight at 4°C: rabbit anti‐MeCP2 (1:1000, Millipore cat no. 07‐013, Burlington, MA, USA) and mouse anti‐Gapdh (1:1000, ThermoFisher cat. no. MA5‐15738, Waltham, MA, USA), followed by the fluorescent secondary antibodies: goat anti‐rabbit (800 nm, 1:5000, LI‐COR, Lincoln, NE, USA) and goat anti‐mouse (680 nm, 1:10,000, LI‐COR, Lincoln, NE, USA). Fluorescence was detected using the Odyssey (LI‐COR, Lincoln, NE, USA) imaging system at the Vanderbilt University Medical Center Molecular Cell Biology Resource (MCBR) Core and then quantified using the Image Studio Lite software (LI‐COR, Lincoln, NE, USA). Values were normalized to Gapdh and compared relative to wild‐type controls.

Monkeys were deeply anesthetized with 0.8 g/kg thiopental sodium one day after P3. Brains were harvested and immediately immersed in 4% ice-cold PFA and incubated at 4℃ on a shaker for 3 days (72 hours). Then, the brains were incubated in 10% sucrose at 4°C on a shaker until submersion and then sequentially incubated in 20% and 30% sucrose. Brains were coronally sectioned (40 μm) in a cryostat at -20℃ (Leica, Wetzlar, Germany). Sectioned brain slices were washed three times in 1X PBS followed by blocking in 5% normal goat serum and 0.3% Triton X-100 in PBS for 2 hours. The brain sections were incubated overnight at 4℃ in Rabbit anti-MeCP2 (1:250, 07-013, Millipore, MA, USA) and Chicken anti-mCherry (1:1,000, B205402, Abcam, Cambridge, U.K.). After washing three times, the sections were incubated in Alexa Fluor 488 goat anti-rabbit IgG (1:400, A-11008, Life Technologies, CA, USA) and Alexa Fluor 594 goat anti-chicken IgG (1:500, A-11042, Life Technologies, CA, USA). Finally, the sections were washed three times and then mounted onto coverslips using a mounting medium with DAPI solution (H-1500, Vector Laboratory, CA, USA). Confocal images were taken by using a Zeiss LSM800 Confocal Microscope (Oberkochen, Germany). MECP2 immunoreactivity was analyzed using the ImageJ software from the National Institutes of Health (MD, USA).

Fluorescence was detected using the Odyssey (LI-COR) imaging system at the Vanderbilt University Medical Center Molecular Cell Biology Resource (MCBR) Core and then quantified using the Image Studio Lite software (LI-COR). Values were normalized to Gapdh and compared relative to littermate controls (WT littermates or Mecp2+/+).

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.
