Brains of E13.5, E16, or E18.5 embryos were processed for histology and immunohistochemistry as previously described (Lysko et al., 2011 (link)). Primary antibodies used included anti-Calbindin D-28k (rabbit; Swant, 1:1000), Caspase-3 (rabbit; Abcam, 1:500), Ki67 (rabbit; Neomarkers, 1:300), anti-Tom-20 (rabbit; Santa Cruz, 1:500), anti-GFP (chicken: Invitrogen, 1:2000). Secondary antibodies included goat anti-rabbit-biotin; Vector Laboratories followed by Streptavidin-Alexa 594; Invitrogen, or anti-rabbit-Alexa 594; Invitrogen anti-chick-Alexa 488; Invitrogen all at 1:2000. Nuclei were counterstained with DAPI.
MGE explants were fixed and immunolabeled as previously described (Lysko et al., 2011 (link); Lysko et al., 2014 (link)) using anti-Tuj1 (rabbit; Neuronal CIII b-tubulin; Covance, 1:1000), anti gamma-tubulin (mouse; 1:200 Sigma), anti-GFP (chicken Invitrogen 1:200), or anti-Ant1 (rabbit) as primary antibodies.

Vps35 Mutant Mice Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols
Vps35 mutant mice have been described previously [9 (link),10 (link),14 (link)], which were backcrossed with C57BL/6 mice for more than 10 generations. Mice were maintained on a standard rodent diet. Vps35 mutations were confirmed by genotyping using PCR and Western blot analysis. All experimental procedures were approved by the Animal Subjects Committee at the Georgia Regents University according to US National Institutes of Health guidelines.
Rabbit polyclonal anti-VPS35 antibody was generated using the antigen of GST-VPS35D1 fusion protein as described previously [9 (link),10 (link),14 (link)]. Rabbit polyclonal antibodies, including anti- ß-galactosidase (Cappel), anti-VPS26 (Abcam),anti-calretinin (Swant), and anti-melanopsin (Advanced Targeting Systems) antibodies, were purchased. Mouse monoclonal antibodies, including anti-neuronal class III ß-Tubulin (Tuj1,Convance), anti-neurofilament (DSHB), anti-calbindin D28k (Swant), anti-glial fibrillary acidic protein (GFAP, Chemicon), anti-rhodopsin (Abcam) and anti-myelin basic protein (MBP, Chemicon) antibodies, were also purchased. In addition, the chicken polyclonal anti- ß-galactosidase antibody (Abcam) and goat polyclonal anti-IBA1 antibody (Abcam) were used. Secondary antibodies were purchased from Jackson Immuno Research Laboratories, Inc. Other chemicals and reagents used in this study were of analytical grade.

Cultured cells were fixed with 4% paraformaldehyde in 0.1 M PBS (pH 7.4) at room temperature (RT) for 15 min. Fixed cells were permeabilized and blocked against nonspecific protein binding (10% normal goat serum, 2% bovine serum albumin and 0.4% Triton X-100 in PBS) for 30 min at RT. The following primary antibodies were used (with specified dilution) for immunodetection: Mouse anti-neuronal nuclei (NeuN) monoclonal (1:500, Chemicon International, USA); mouse anti-tubulin, beta III isoform monoclonal (1:1000, Chemicon); anti-Calbindin D-28K (mouse monoclonal, 1:1000, Swant, Bellinzona, Switzerland and rabbit polyclonal, 1:1000, Chemicon); mouse anti-synaptophysin monoclonal (1:10,000, Chemicon). The primary antibodies were incubated overnight at 4 °C for binding, and then detected with the appropriate Alexa-conjugated secondary antibodies (Molecular Probes, Inc., 2 h incubation at RT). Actin was visualized by Alexa Fluor 594 conjugated phalloindin (1:1000, Invitrogen, USA).

Paraformaldehyde-fixed brains were sectioned coronally (at 20μm thickness) using a sliding microtome (CM1900; Leica, Germany). For immunohistochemistry (IHC), slices were blocked with phosphate-buffered saline (PBS) containing 10% fetal bovine serum (FBS) and 0.5% Triton X-100 for 1.5 hours, and incubated with anti-GFAP (Z0334; Dako Cytomation, Denmark), anti-Iba1 (019-19741; Wako, Japan), anti-YM1 (#01404, Stemcell Technologies, Canada) and anti-Calbindin-D28K (CB38; Swant, Switzerland) antibodies at 4°C overnight. Slices were then incubated with Alexa Fluor 488-conjugated AffiniPure Goat anti-rabbit IgG secondary antibody (111–545–003; Jackson ImmunoResearch, USA) for 1.5 hours. For Thioflavin-S staining, slices were stained with 0.015% Thioflavin-S (T1892; Sigma, USA) for 15 minutes at room temperature. After mounting, slides were imaged using a Zeiss fluorescence microscope (Axio Observer A1; Zeiss, Germany).

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.
