Full Methods

Primary Antibody: ABIN2857018

Secondary Antibody: Donkey-anti-Rabbit-Cy3

Full Protocol:

• Wild-type mouse adult brain was dissected, fixed in 4% PFA for over/night, saturated in 30% sucrose, mounted in Cryo, and sectioned into 12µm sections.
• Immunostaining for Cryo Sections:
• • Dry slides at 50-55°C for 15-30min (or RT for 30min).
  • Wash with PBS 5min X 3 (shake gently).
  • Block with 10% Normal Donkey Serum (NDS) at RT for 1h.
  • Incubate with ABIN2857018 diluted 1:10 - 1:800 in 2% NDS at 4°C overnight.
  • Wash with PBS 5min X 3.
  • Incubate with the secondary antibody Donkey-anti-Rabbit-Cy3 together with DAPI 1:100 at RT for 1h (prepared in 2% NDS), cover the chamber with foil.
  • Wash with PBS 5min X 3.
  • Add three drops of water-based Immu-mount.
  • Cover with 24 X 60 cover glass.
• Imaging:
• • Images were taken using a Zeiss Axio2-Imaging system, 20X-0.5NA-Dry Dye-1004-072 objective, DAPI and Cy3 channel.

Experimental Notes: ABIN2857018 worked the best at 1:200. At 1:400, or 1:800, it seems to lose some signals in some cells.

Background: The protein encoded by this gene is structurally similar to G protein-coupled receptors and is highly expressed in endothelial cells. It binds the ligand sphingosine-1-phosphate with high affinity and high specificity, and suggested to be involved in the processes that regulate the differentiation of endothelial cells. Activation of this receptor induces cell-cell adhesion.
