    Product Description

    Dinactin is a macrotetrolide antibiotic that acts as an ionophore for monovalent cations, such as K+, NH4+, and Rb+.1 It is commonly used to study membrane properties.1,2 Dinactin is a component of a macrotetralide-rich antifungal mixture produced by Streptomyces.3 Dinactin inhibits T-cell proliferation and cytokine production in vitro and reduces pulmonary eosinophilia in antigen-challenged mice.4

    WARNING This product is not for human or veterinary use.
