Replaces Prod. #: BML-CM109

A steroidal inhibitor of cardiac sodium pumps (Na⁺/K⁺ ATPase) which has been recognized as an endogenous adrenal hormone. In the CNS it can be used as a tool to induce in vivo excitotoxicity. Ouabain, as well as other endogenous digitalis-like compounds, can down-regulate the expression of 14-3-3 proteins in rat lens.
