Ionomycin free acid is an antibiotic selective calcium ionophore, which can extract calcium ions from aqueous phase to organic phase. In addition, Ionomycin free acid acts as a transport carrier, which helps transport cations across solvent barriers. Studies indicate that this antibiotic can transport other ions such as Mg, Sr, and Ba with a weaker affinity. It is known that Ionomycin free acid is produced by Streptomyces conglobatus. Furthermore, Ionomycin free acid is a beneficial tool in research to raise intracellular calcium levels. Also this antibiotic can be used to study the calcium transport across the plasma membrane.Ionomycin is more effective than A23187 as a Ca++ionophore. Ionomycin is used in research on Ca++ transport across biological membranes; Ionomycin induces apoptotic degeneration of embryonic cortical neurons Ionomycin free acid is an antibiotic selective calcium ionophore, which can extract calcium ions from aqueous phase to organic phase.
