Enzo Life Sciences Sphingosine-1-phosphate, D-erythro, (1mg), CAS Number: 26993-30-6
Endogenous signaling molecule. Formula: C18H38NO5P. MW: 379.5. CAS Number: 26993-30-6. Purity: ≥98% (TLC). Solubility: Sparingly soluble in 1:1 ethanol:water. Addition of small amounts of acetic acid may help dissolve this product. Soluble in warm methanol. For delivery of sphingosine-1-phosphate to cells, prepare a 125μM stock in 4mg/ml BSA as follows: Dissolve sphingosine-1-phosphate (S-1-P) in methanol (0.5 mg/ml). This may require boiling (65°C), with occasional replacement of evaporated methanol. Crushing of solid prior to addition of methanol and crushing and stirring during heating is helpful. Aliquot desired amounts of methanol stock to tubes. Evaporate the solvent with a stream of nitrogen, swirling to deposit a thin film 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 125 µM stock. Long Term Storage: -20°C
