Calcium Ionomycin; (4R,6S,8S,10Z,12R,14R,16E,18R,19R,20S,21S)-11,19,21-Trihydroxy-4,6,8,12,14,18,20-heptamethyl-22-[(2S,2’R,5S,5’S)-octahydro-5’-[(1R)-1-hydroxyethyl]-2,5’-dimethyl[2,2’-bifuran]-5-yl]-9-oxo-10,16-Docosadienoic Acid Calcium Salt

Antibiotic that acts as a potent and selective calcium ionophore; more effective than A23187. Ionomycin binds Ca2+ in the 7.0-9.5 pH range with the resulting complex exhibiting intense UV absorption. Ionomycin Calcium is a polyether antibiotic obtained from Streptomyces conglobatus by solvent extraction. It is different from other antibiotics of its class as it absorbs UV light at 300nm maximum. Gram-positive antibiotic.
