General description

A cell-permeable tumor-promoting sesquiterpene lactone that releases Ca2+ by inhibiting endoplasmic reticular Ca2+-ATPase (IC50 = 4 - 13 nM). Does not increase inositol phosphates and has no significant effect on protein kinase C. Increases Ca2+-dependent Na+ influx in human platelets in a dose-dependent manner. Activates apoptosis in rat thymocytes and induces apoptosis in human hepatoma cells.Specifically inhibits the fusion of autophagosomes with lysosomes, and induces autophagy.

Biochem/physiol Actions

Cell permeable: yes
Reversible: no

Packaging

Packaged under inert gas

Physical form

A 10 mM (2 mg/307 µL) solution of Thapsigargin (Cat. No. 586005) in DMSO.
