Ordering Information

Biological Activity

CYM50308 is a potent and selective sphingosine-1-phosphate receptor 4 (S1P4) agonist with an EC50 of. Activation of S1P4 signaling modulates downstream G protein-coupled pathways, regulating immune cell trafficking, differentiation, and cytoskeletal reorganization. The compound demonstrates high selectivity for S1P4 over other S1P receptor subtypes, providing a useful chemical probe to investigate S1P4-mediated cellular responses and physiological functions.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
