Thapsigargin is an inhibitor of sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA, IC50 = ~30 nM for the rat liver microsomal enzyme), an ER stress inducer, and a sesquiterpene lactone that has been found in Thapsia. It increases intracellular calcium levels in isolated rat hepatocytes (EC50 = ~80 nM) and...

Colorless to white amorphous powder. Soluble in DMSO or 100% ethanol. Chemical. CAS: 67526-95-8. Formula: C34H50O12. MW: 650.8. Isolated from Thapsia garganica. Intracellular Ca2+ signaling probe. Specific and sensitive inhibitor of SERCA. Non-TPA/PMA tumor promoter. Histamine release inducer. Apoptosis inducer....

Thapsigargin is isolated from Thapsia garganica. It is a cell permeable intracellular calcium releaser and tumor promoter.

Potent, cell permeable IP3-independent intracellular calcium releaser. Solubility: Soluble in DMSO or ethanol. Storage and Stability: May be stored at RT for short-term only. Long-term storage is recommended at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap.

Thapsigargin is a non-competitive, cell permeable inhibitor of calcium transport by SERCAs (IC50 values are cell type-dependent and range from ~2-80 nM). Inhibition of SERCAs leads to an increase in intracellular calcium, which has been linked to cell activation, release of histamine from mast cells, and increased...
