Echelon offers a unique selection of sphingosine 1-phosphate analogs labeled at the terminus of the alkyl chain with biotin or fluorescent groups. All compounds have the natural erythro stereochemistry and are synthesized from chiral precursors.
Storage
Sphingosine 1-phosphate tetramethylrhodamine (S1P TAMRA) is relatively stable at room temperature as a solid. It is best stored as a dried solid, protected from light at -20 C. Solutions/emulsions should be kept at -20 C. Storage in basic buffers (pH > 9.0) or acidic buffers (pH < 4.0) may cause decomposition.
