S1P receptor ligand

Saturated analog of sphingosine-1-phosphate. Induces chemotaxis in HUVECs. May be used as a negative control for intracellular effects of S1P. Rapidly dephosphorylated by a sphingosine phosphatase in cultured human fibroblasts. Ligand for S1P (EDG) receptors.

Specific Protocol

For delivery of dihydrosphingosine-1-phosphate to cells, prepare a 125µM stock in 4mg/ml BSA as follows: Dissolve dihydrosphingosine-1-phosphate (HSPP) in methanol/THF/water (60/30/10) (0.5mg/ml). This may require boiling (75°C), with occasional replacement of evaporated methanol. Crushing of solid prior to addition of solvent and crushing and stirring during heating is helpful. Aliquot desired amounts of stock solution to tubes. Evaporate the solvent with a stream of nitrogen, swirling to deposit a thin film of HSPP on the inside of the tube. Aliquots may be stored at –20 °C at this point or dissolved with enough 4mg/ml BSA (fatty acid free Bovine Serum Albumin in water; 37°C, 30 min. with repeated vortexing) to make 125µM stock.
