Biological Data

Biological description

Monensin is an ionophore and protein transport inhibitor which facilitates the transmembrane exchange of sodium ions for protons.

Monensin disrupts the trans-Golgi transport of proteins by interacting with Golgi membrane Na+ + /H+ transport.It also neutralizes acidic intracellular compartments and disrupts the Golgi apparatus structure and slows down and reduces the process of endocytosis.


Uses

Monensin is commonly used for intracellular staining of cytokines for flow cytometry by inducing an accumulation of cytokines in the golgi complex. Monensin also shows antibiotic action and induces apoptosis.


Brefeldin A (BFA) also available.

Additionally shows inhibitor activity towards some Coronaviruses (CoVs) (e.g. (MERS-CoV)).
