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.

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

Wearable health monitoring has garnered considerable interest from the healthcare industry as an evolutionary alternative to standard practices with the ability to provide rapid, off-site diagnosis and patient-monitoring. In particular, sweat-based wearable biosensors offer a noninvasive route to continuously monitor

We have examined the binding of the fluorescent Ca indicator indo-1 to cellular protein in permeabilized ventricular myocytes and also to soluble and particulate myocyte protein. Using either a filtration technique or equilibrium dialysis, and conditions similar to those in

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

In this work, ion-selective electrodes for calcium ion were investigated. Two ionophores were used in the membranes: ETH 1001 and ETH 129. An internal filling solution buffered for primary ion was used that allowed the lower detection limit to be
