Molarity Calculator

Monensin (Monensin A), an orally active antibiotic, is an ionophore that mediates Na⁺/H⁺ exchange. Monensin is a potent Wnt signaling inhibitor. Monensin causes a marked enlargement of the multivesicular bodies (MVBs) and regulates exosome secretion. Monensin can be used for bacterial, fungal, and parasitic infections research, and shows anticancer effects.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Monensin sodium) usually boasts enhanced water solubility and stability.

Description

In Vitro

Monensin (1-5 μM; 48 h) results in a marked decrease in viability in a dose-dependent manner^[1].
Monensin (1-5 μM; 24 h) shows a statistically significant induction of apoptosis^[1].
Monensin (0.1-1 μM; 24 h) inhibits pEGFR and its downstream targets pAKT and pERK^[1].

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
