Pregnant females were sacrificed by cervical dislocation, the embryos dissected out of the uterus and fixed o/n in 4% paraformaldeyde (PFA) at 4°C. Adult animals were anaesthetized with Avertin and perfused intracardially with 4% PFA. Brains were dissected out, post-fixed o/n in PFA at 4°C and embedded in either 2.5% agarose or tissue-tek for sectioning with vibratome or cryostat, respectively.
For immunostaining specimens were incubated with primary antibodies o/n at 4°C in PBS containing 5% heat-inactivated lamb serum and 0.5% Triton X-100. Primary antibody dilutions: rabbit anti-5-HT (Sigma) 1∶500; chicken anti-eGFP/eYFP (Abcam) 1∶1000; mouse anti-calbindin-D-28K (Sigma), 1∶200. Fluorescent-conjugated secondary antibody were used as follow: Rhodamine Red-X goat anti-rabbit IgG 1∶500; Alexa Fluor 488 goat anti-chicken IgG 1∶200; Rhodamine Red-X goat anti-mouse IgG 1∶500 (all by Molecular Probes). Cell nuclei were counterstained with DAPI (Sigma), 0.5 µg/ml.

Immunohistochemistry of Testicular Tissue

Freshly dissected testes were fixed in 4% paraformaldehyde, embedded in paraffin and sectioned at 5 μm. The sections were deparaffinized in xylene and an ethanol series. Antigen retrieval was performed by boiling the sections for 20 min in 10 mM tribasic sodium citrate, pH 6. The samples were washed in phosphate-buffered saline (PBS) and then immersed in 0.4% Triton X-100 for 10 min before being blocked with a buffer (3% bovine serum albumin in PBS) for 30 min. The sections were incubated overnight at 4°C with the primary antibodies (5 μg·mL-1), and then placed in 1/1000 dilutions of Rhodamine Red™-X goat anti-rabbit IgG (Molecular Probes) for 30 min at room temperature. DNA was stained with DAPI, and the sections were mounted and visualized by fluorescence microscopy (DMLB, Leica).

Immunohistochemistry of GALNS and Collagen X

Tissues were processed into paraffin, sections cut on a Leica RM 2135
rotary microtome and dried overnight at 36°C on Fisher Superfrost Plus
slides. Sections were deparaffinized and rehydrated, and antigen retrieval
performed (120°C, 3 minutes) using DIVA Decloaker (Biocare Medical).
After washing in distilled water twice for 3 minutes, sections were blocked in
PBS containing 5% normal goat serum, 1% bovine serum albumin, and 0.25% triton
X-100 in a humidified chamber for 1 hour at RT, then incubated in primary
antibody GALNS (Epitomics) 1:50, normal rabbit IgG in block solution or Collagen
X (Santa Cruz Biotechnology) 1:100 for 2 hours at RT. After 3 washes for 5
minutes in PBS, sections were incubated in goat anti-rabbit IgG Rhodamine Red-X
(Invitrogen) 1:300 or Alexa Fluor 488 (Jackson Immunoresearch) in block solution
for 1 hour at RT in the dark, washed 3 times for 5 minutes in PBS in the dark,
rinsed in distilled water, and coverslipped in Prolong Gold with DAPI
(Invitrogen).

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.
