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%
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.
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.
dilute citrate or acetate buffer: soluble1 mg/mL (dissolve at pH 4-5. Aqueous solutions, pH 4-5, are stable if stored frozen.)
strong acid or alkaline solutions: unstable (destroyed by boiling at pH 2.)
