Application

Tetrodotoxin has been used as standard during HPLC-based analysis of biotoxins from P. punctata tentacles whole crude extract (PHY-N). Tetrodotoxin has also been used to study its effects on low-threshold transient (LTT) Ca²⁺ currents in rat hippocampal interneurons.

Biochem/physiol Actions

Reversible, selective blocker of Na⁺ channels.

Reversible, selective blocker of Na⁺ channels; blocks propagation of impulses in excitable membranes. Used to characterize sodium channels in excitable membranes and to study the role of sodium channels in normal physiology and disease.

Preparation Note

Tetrodotoxin is soluble in dilute citrate or acetate buffer at 1 mg/ml (pH 4-5). Aqueous solutions are stable at pH 4-5 if stored frozen. However, tetrodotoxin is unstable in strong acid or alkaline solutions and is destroyed by boiling at pH2.
