Application

Selected application examples

Calcium ionophore II (ETH 129) was used in preparing calcium selective minielectrodes which are used in determination of dissociation constant (K_d).

Suitable for intracellular calcium measurements.

Lipophilic ionophore for Ca²⁺-selective electrodes with detection limit in the sub-nanomolar range. Extremely efficient carrier of Ca²⁺-ions; induces a selectivity in membranes for Ca²⁺ over Mg²⁺ by a factor of about 10⁴.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
