General description

Visit our Sensor Applications portal to learn more.

Biochem/physiol Actions

Activates protein kinase C in hepatocytes.
Uncouples oxidative phosphorylation. Inhibits 2,4-dinitrophenol−stimulated ATPase. Action reversed by adding serum albumin.

Other Notes

Oleic acid is often used as additive in ionophore PVC-membranes. The sensitivity is thus improved in many cases
