• Brand: TRC
• Description: Applications A widely used inhibitor of the ubiquitous sarco-endoplasmic reticulum Ca(2+)-ATPases in mammalian cells. It acts as a potent, cell-permeable, IP3-independent intracellular calcium releaser that blocks the transient increase in intracellular Ca2+ induced by angiostatin and endostatin. It induces apoptosis by disrupting intracellular free Ca2+ levels.References Treiman, M. et al.: Trends Pharmacol. Sci., 19, 131 (1998); Korge, P. et al.: Eur. J.
