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).[1]
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[2].

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

A calcium ion-selective PVC membrane electrode based on neutral carrier n,n,n',n'-tetracyclohexyl-3-oxapetanediamide, using di-(2-ethylhexyl)phthalate as the plasticizer and potassium tetrakis (4-chlorophenyl) borate as the additive is reported in this paper. The ion selective membrane consists of 1 wt% of the Ca2+

An analytical system based on ion-selective field effect transistors (ISFETs) with Ca(2+) ion selective photocurable membranes is developed to offer a semiautomatic analysis of serum calcium concentration of ruminants. Optimisation of ion-sensitive membrane composition containing different copolymerised plasticizers was performed
