What is ETH 1001?
Description
Calcium ionophore I is a Ca2+-selective ionophore for biological membranes that can be used in microelectrodes for the determination of intracellular Ca2+-activities and of slowly changing Ca2+ levels.
What are the applications of Application
CA 1001 is a neutral ionophore carrier that exhibits high selectivity for Ca2+ ions
Purification Methods
This is a neutral Ca selectophore. It can be purified by thick layer (2mm) chromatography (Kieselgel F245) and eluted with Me2CO/CHCl3 (2:1). [Ammann et al. Helv Chim Acta 56 1780 1973, Simon & Carafoli Methods Enzymol 56 439 1977.]
