Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Product Description
Xestospongin C ((-)-Xestospongin C) is a selective, reversible inositol 1,4,5-trisphosphate receptor (IP3R) inhibitor. Xestospongin C acts as an inhibitor of the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA) pump of internal stores. Xestospongin C blocks IP3-induced Ca2+ release from cerebellar microsomes with an IC50 of 358 nM. Xestospongin C is a valuable tool for investigating the structure and function of IP3Rs and Ca2+ signaling in neuronal and nonneuronal cells.
