As a professional manufacturer & exporter, we supply tetrodotoxin which features are as below:


Appearance: White powder indefinite crystal


Purity (HPLC): TTX 99.9% , not less than 99%


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.


Tetrodotoxin has been used as standard during HPLC-based analysis of biotoxins fromP. punctata tentacles whole crude extract (PHY-N)1. Tetrodotoxin has also been used to study its effects on low-threshold transient (LTT) Ca2+ currents in rat hippocampal interneurons2.

Biochem/physiol Actions

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.
