Dinactin
Application Notes
Dinactin is a member of the macrotetrolide complex produced by a range of Streptomyces species. It is a monovalent cation ionophore with high selectivity for ammonium and potassium. Dinactin inhibits T-cell proliferation induced by IL-2 and cytokine production at nanomolar levels for IL-2, IL-4, IL-5 and interferon-γ. Dinactin has not previously been available for intensive investigation.
