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.

Analytical and bioanalytical chemistry, 385(8), 1477-1482 (2006-07-19)
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

In this study we used tightly-coupled mitochondria from Yarrowia lipolytica and Dipodascus (Endomyces) magnusii yeasts, possessing a respiratory chain with the usual three points of energy conservation. High-amplitude swelling and collapse of the membrane potential were used as parameters for

We have investigated the ability of the neutral ionophore ETH 129 to translocate Ca2+ across artificial and biological membranes. ETH 129 induces Ca2+ transport across planar lipid bilayer. The zero-current membrane potential in a gradient of Ca2+ concentration exhibits Nernst

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
