Chemische Eigenschaften

Verwenden
Ionomycin was isolated from Streptomyces conglobatus as a potent Gram positive antibiotic . During isolation, it was recognised that ionomycin exhibits a very high affinity and selectivity for calcium ions, suggesting the metabolite acts as a calcium ionophore. More recently, ionomycin has been used in cell biology as a universal calcium ionophore to explore the role of calcium regulation in the cell.
Definition
ChEBI: A very long-chain fatty acid that is docosa-10,16-dienoic acid which is substituted by methyl groups at positions 4, 6, 8, 12, 14, 18 and 20, by hydroxy groups at positions 11, 19 and 21, and by a (2',5-dimethyloctahydro-2,2'-bifuran-5-yl)ethanol group at
osition 21. An ionophore produced by Streptomyces conglobatus, it is used in research to raise the intracellular level of Ca2+ and as a research tool to understand Ca2+ transport across biological memb
anes.
Allgemeine Beschreibung
Highly specific for divalent cations (Ca
2+ > Mg
2+ >> Sr
2+ = Ba
2+). More effective than antibiotic A23187 as a mobile ion carrier for Ca
2+. Complexes with Ca
2+ between pH 7 and 9.5, causing significant absorption in the UV range; however, in contrast to A23187 (Cat. No. 100105), it is not fluorescent. Useful for studies of Ca
2+ transport across biological membranes and measurement of cytoplasmic free Ca
2+. Induces apoptotic neuronal degeneration in embryonic cortical neurons. Also induces cell cycle arrest in the G
1 interval of mature Burkitt lymphoma cell lines.
