Immunofluorescence was performed as previously described [17 (link)]. Briefly, brains were sectioned at a thickness of 30 µm and left 1 h in blocking solution (10% normal donkey serum, 0.3% Triton-X1000, 0.04% NaN3 in PBS). Following the blocking step, the sections were incubated with primary antibodies (diluted in blocking solution) overnight at 4 °C. The primary antibodies used were rabbit anti-Ascl1 (Cosmo Bio Co., CAC-SK-T01-003, concentration 1:250), goat anti-Dcx (Santa Cruz, SC-8066, concentration 1:500), mouse anti-NeuN (Millipore, MAB377, concentration 1:500), rabbit anti-S100β (DAKO, Z0311, concentration 1:200, antibody was directly conjugated with fluorophore Alexa-647) and rat anti-Ki67 (eBioscience, 14-5698, concentration 1:1000). Subsequently, the sections were washed three times for 5 min in PBS before incubation with secondary antibodies (1:500 in blocking solution) against the species for the specific primary antibodies and conjugated with the fluorophores Alexa-488, Cy3 and Alexa-647. For Ascl1 detection we used a Tyramide Signal Amplification (TSA) protocol (PerkinElmer, NEL701001KT).

Mice were deeply anesthetized with ketamine/xylazine (150/15 mg/kg) and transcardially perfused with cold 0.1 M phosphate buffered saline (PBS), followed by 25mL of cold 4% paraformaldehyde in PBS. Brains were postfixed overnight in 4% paraformaldehyde at 4°C, then cryoprotected in 30% sucrose in PBS, and stored at 4°C. Coronal sections (35 µm) were cut through the entire hippocampus on a cryostat and stored in PBS with 0.1% NaN3.
For doublecortin (DCX) immunohistochemistry, sections were blocked in 10% normal donkey serum in 0.1M phosphate-buffered saline (PBS) with 0.25% Triton X-100 for 2h at room temperature. After overnight incubation with primary antibodies (goat anti-DCX, 1:500, Santa Cruz #SC 8066; mouse anti-NeuN 1:500, Millipore MAB377), sections were washed in PBS and incubated with secondary antibodies (Cy3-conjugated donkey anti-goat and Cy5-conjugated donkey anti-Mouse, 1:500, Jackson ImmunoResearch) for 2h at room temperature. Sections were mounted on slides, dried, rinsed in water, and cover slipped using aqueous mounting medium.

Avian Neuronal Immunolabeling Protocol

Immediately after capture (still on the field) and under deep isoflurane anesthesia, birds were perfused transcardially with phosphate buffered saline 0.1M followed by aldehyde fixatives (4% paraformaldehyde, 0.1 M phosphate buffer, pH 7.2–7.4). Brains were dissected, stored in phosphate buffered saline 0.1M and cut by Vibratome (Leica VT1000S) or freezing microtome (Sliding Microtome, Reichert Jung) in the coronal plane. Six anatomical series of sections (6 parallel series), cut at 60 or 80μm in the freezing microtome or vibratome respectively, were immunolabeled for NeuN or DCX or stained by Nissl. Free-floating sections were immunolabeled with anti-doublecortin antibody (Santa Cruz SC-8066) or NeuN antibody (MiliporeSigma, MAB377), and mounted on glass slides coated with an aqueous solution of gelatin (10%) and chromium potassium sulfate (0.5%). Sections were air-dried at room temperature, dehydrated, cleared in alcohol/xylene series and covered with 50% entellan (Entellan® Novo 107961, Merck Milipore) diluted in xylene and cover slipped.

Peptide Competition Assay for DCX Antibodies

To determine the specificity of the goat anti-DCX antibody (Santa Cruz, sc-8066) and the guinea-pig anti-DCX antibody (Chemicon, AB5910) a peptide competition assay was performed. The DCX peptide was no longer available at Chemicon. As such, both antibodies were submitted to a competition assay with the DCX peptide provided by Santa Cruz Biotechnology (sc-8066). A 1:5 solution of anti-DCX antibody and anti-DCX peptide (sc-8066P, Santa Cruz) was incubated at room temperature for 1 h. The preparation was then diluted in 0.3% Triton and each section was covered with 50 μl and incubated at room temperature for 3 h. Following incubation, slides were washed successively three times for 5 min in PBS (10 mM). Each section was then incubated for 30 min at 37°C with 50 μl of the secondary antibody Alexa488 donkey anti-Goat (1:1,000, Invitrogen) or Alexa488 anti-guinea pig (1:500, Jackson Immuno Research) diluted in 0.3% Triton in 10X PBS. After incubation, slides were washed successively three times for 5 min in 10X PBS. Sections were imbedded in custom-made anti-fade solution (p-Phenylenediamine and glycerol in PBS solution) and cover-slipped with micro cover glasses (VWR Scientific).

Mice were transcardially perfused with 4% paraformaldehyde. The brains were removed, post-fixed overnight, and cut into 50 μm coronal and sagittal sections using a vibratome (Leica Microsysteme, Rueil Malmaison, France). Immunofluorescent labeling was performed on sections or on cultured cells fixed with paraformaldehyde 4%. The following antibodies were used: anti-GFP (rabbit, 1/500; Life Technologies, A11122. Chicken, 1/500; Aves Labs GFP-1020), anti-DCX (goat, 1/100; Santa Cruz Sc-8066), anti-MBP (mouse IgG1, 1/500; Chemicon MAB384), anti-GFAP (mouse IgG 1/1,000; Sigma G3893), anti-OLIG2 (rabbit, 1/500; Chemicon AB 9610), anti-SOX9 (goat, 1/200; R&D AF3075), anti-PDGFRα (rat, 1/250; Chemicon CBL1366), anti-CC1 (mouse, 1/500; Calbiochem OP80), anti-CASPR/PARANODIN (rabbit, 1/500; L51, gift from Dr Goutebroze), anti-TCF4 (mouse IgG2a, 1/500; Millipore 05–511), anti-PSA-NCAM (mouse, ½; supernatant produced in our laboratory), anti-NEUROFILAMENT-160 (mouse, 1/500; Sigma N5264), and anti-βIV-SPECTRIN (mouse clone 393/2, 1/500; NeuroMab AB_2315816). The sections and cells were incubated with appropriate Alexa-conjugated secondary antibodies (1/500; Jackson ImmunoResearch Laboratories) then counterstained with Hoechst 33,342 (1/1,000; Sigma). Images were captured with a Zeiss apotome system (20× and 60× objectives) and a Zeiss 510 confocal (60× objective).

Slice preparation, immunostaining, and image acquisition and analysis were as previously described (Platel et al., 2009 (link)). Primary antibodies included: anti-VGAT1 (mouse, 1:500, Synaptic Systems), anti-neurofilament (NF, 1:500, MAB5166) anti-DCX (goat or rabbit, 1:100, Santa Cruz, SC8066 and SC28939), and anti-GLAST (guinea pig, 1:500, Chemicon). Each staining was replicated at least in 4–5 slices from three different mice. The appropriate secondary antibodies were Alexa fluor series (1:1000, Invitrogen, USA) or Cyanine series (1:500, Jackson Labs). Z-section images (spaced by 1–2 μm over 10–20 μm) were acquired on a laser-scanning confocal microscope (Olympus FluoView 1000) with a 20× dry objective (N.A. 0.75) or a 60× oil objective (N.A. 1.42). Images were analyzed and reconstructed using Imaris 4.0 (Bitplane AG, Switzerland) and Photoshop CS3 (Adobe, USA).

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.
