Background:

Calcium Ionophore I, also known as CA 1001 or ETH 1001, is a Ca2+-selective ionophore [1][2].

Ionophores can selectively change the ionic permeability of a membrane and therefore can be used to mimic the properties of the ion carriers normally found in biological membranes and to study membrane function [2].

Calcium Ionophore I is a Ca2+-selective neutral carrier. In Ca2+ loaded IOVs derived from human RBCs, ETH 1001 promoted Ca2+ flux across RBC membranes. The amount of Ca2+ in cells treated with ETH 1001 was significantly higher than in control cells. In the presence of external Ca2+, ETH 1001 was capable of transporting Ca2+ into RBCs [3]. CA 1001 was also used to construction of the Ca2+-selective membrane microelectrode [4][5].
