应用

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.

生化/生理作用

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.

制备说明

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.

Not only from our daily experience but from learning experiments in animals, we know that the establishment of long-lasting memory requires repeated practice. However, cellular backgrounds underlying this repetition-dependent consolidation of memory remain largely unclear. We reported previously using organotypic

Phyllorhiza punctata (P. punctata) is a jellyfish native to the southwestern Pacific. Herewith we present the biochemical and pharmacological characterization of an extract of the tentacles of P. punctata. The tentacles were subjected to three freeze-thaw cycles, homogenized, ultrafiltered, precipitated

Neurotoxin receptor site 1, in the outer vestibule of the conducting pore of voltage-gated sodium channels (VGSCs), was first functionally defined by its ability to bind the guanidinium-containing agents, tetrodotoxin (TTX) and saxitoxin (STX). Subsequent studies showed that peptide micro-conotoxins

The potent neurotoxin tetrodotoxin (TTX) has been identified from taxonomically diverse marine organisms. TTX possesses a unique cage-like structure, however, its biosynthesis has yet to be elucidated. Biosynthetic studies in the TTX-producing newt Taricha torosa, and in bacterial genera, including
