To evaluate synaptic vesicles, retinal expression of synaptophysin was assessed. For fluorescence staining, samples were pre-embedded in 3% agar in deionized water. Vibratome sections (50 μm) were collected and washed several times in PBS. Sections were incubated in 10% normal donkey serum in PBS for 1 h at room temperature to block nonspecific binding activity, then with anti-rabbit synaptophysin (Cell signaling, Danvers, MA, USA) overnight at 4°C. After several washes with PBS, sections were incubated with goat anti-rabbit Alexa 546 (Molecular Probes). For double-labeling studies, sections were incubated with anti-mouse PKCα (Santa Cruz Biotechnology, Santa Cruz, CA), parvalbumin (Sigma, St. Louis, MO), calretinin (Millipore, Temecula, CA, USA), or SMI-32 (Covance, Emeryville, CA, USA) in 0.1 M PBS containing 0.5% Triton X-100 overnight at 4°C, rinsed for 30 min with 0.1 M PBS, and incubated with goat anti-mouse Alexa 488 (Molecular Probes) for 1 h 30 min at room temperature. After further washes in 0.1 M PB for 30 min, the sections were mounted using VectaShield Mounting Medium with DAPI (Vector Laboratories, H-1200). Slides were washed, covered with coverslips, and examined by confocal laser scanning microscopy (Zeiss LSM 510; Carl Zeiss Co. Ltd.).

Nrp2+/+ (wild-type), Nrp2+/− (heterozygote) and Nrp2−/− (homozygote) mice aged 3–6 months (average age of all genotype groups: 3.7 ± 0.95 months, four females and five males), when mice are considered to be in the mature adult stage [34 ], were subjected to transcardial perfusion with 4% paraformaldehyde (PFA). Brains were dissected, postfixed for 2 h in 4% PFA and then imbedded in OCT medium. Brains were sectioned on a cryostat at 20 μm thickness at 200 μm intervals through the anterior to the posterior extent of the hippocampus and cortex along the coronal plane. Sections were processed for immunocytochemistry as previously described [35 (link)], with the following modification. Coverslips were mounted on microscope slides using Mowiol (cat. No. 81381 Aldrich), plus 10% p-Phenylenediamine (PPD, cat No. 78460) anti-fade mounting media. Primary antibodies used were: mouse monoclonal anti-Parvalbumin (1.5:500, Swant, PV235); mouse monoclonal anti-Parvalbumin (1:750, Sigma, P3088); rabbit polyclonal anti-neuropeptide Y (1:1000, Abcam, ab30914); rat monoclonal anti-Somatostatin (1:150, Millipore, MAB354) and for visualization, AlexaFluor 488 or Cy5 (1:500, Jackson Immuno Research Laboratories); AlexaFluor 546 (1:500 Invitrogen).

The mouse monoclonal antibody to L-ENK (Sera Labs, Crawley Down, UK) has been characterized using preadsorption controls and immunoblots where it recognizes L-ENK and to a lesser extent DYN (1-13, 1-17) and Met5-ENK, but not α, β and γ endorphin [7 ;27 (link)]. The guinea pig polyclonal antibody against DYN B was purchased from Peninsula Laboratories (Belmont, CA) and has been characterized for specificity using preadsorption [31 (link);40 (link)]. Previous tests [44 (link)] determined the dilution of the L-ENK and DYN antibodies that yielded optimal detection of intensity variations.
The mouse monoclonal antibody to parvalbumin (Sigma, St. Louis, MO) has been characterized using Western blot, double immuno-diffusion methods and preadsorption controls [4 (link);21 (link)]. The rabbit polyclonal antibody against NPY (Peninsula Laboratories) has been characterized using immunodot blots [28 (link)]. The rabbit polyclonal antibody to cholecystokinin (#8988; supplied by Dr. John Walsh, Veterans Administration, CA) has been shown to be specific using immunodot blots and preadsorption controls [5 (link)]. The optimal dilution of the CCK antibody for detecting intensity variations was determined using previously described methods [6 (link)].

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.
