Application
Selected application examples
Calcium ionophore II (ETH 129) was used in preparing calcium selective minielectrodes which are used in determination of dissociation constant (Kd).
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.
Suitable for intracellular calcium measurements.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

Divalent cations are required for many essential functions of mitochondrial metabolism. Yet the transporters that mediate the flux of these molecules into and out of the mitochondrion remain largely unknown. Previous studies in yeast have led to the molecular identification

Ultrathin metallic WS2 (M-WS2) nanosheets and semiconductive WS2 (S-WS2) nanosheets were exfoliated and for the first time employed as ion-to-electron transducing layer to construct an all-solid-state ion-selective electrode. Importantly, we found that the transducing efficiency of WS2 nanosheet-based solid-contact layer is
