How to use

In Vitro:

Preincubation of the cells with the Na+ ionophore ETH 2120 not only stimulated caffeate reduction, but completely abolished ATP synthesis. Addition of ETH 2120 to cells in the steady state of caffeate reduction immediately dissipated the intracellular ATP level. Lactate-sulfate grown cells are insensitive to the Na+ ionophore, ETH 2120. ETH 2120 ligand is a very effective receptor for the Eu3+ and Am3+ cations and can be considered as a potential extraction agent for nuclear iste treatment.
