2,599 items of experiments involved in drug testing protocols ((2R)-amino-5-phosphonovaleric acid (APV), bicuculline (BIC), 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX), tetrodotoxin (TTX), octanol (OCT), carbenoxolone (CBX), brain-derived neurotrophic factor (BDNF), etc.).
Tetrodotoxin (TTX) is a nonproteinaceous neurotoxin that prevents the generation of action potentials in nerve and skeletal muscle by binding to the pore region of voltage-gated sodium channels, leading to fatal asphyxiation [1, 2].
algae could be tolerant to bile salts and may produce tetrodotoxin [42], exoenzymes, or siderophores [8], which are considered virulence factors.
One potent [Na.sup.+] channel blocker that has shown sustained analgesia long after treatment termination is tetrodotoxin, a neurotoxin isolated from puffer fish.
The muscle strips were equilibrated for 1 hour in 37[degrees]C oxygenated KRB, followed by an additional 1-hour incubation in 37[degrees]C oxygenated KRB with 0.3 [micro]M tetrodotoxin. For automated capillary electrophoresis and Western blotting, the muscles were submerged into ice-cold acetone/10 mM DTT/10% (w/v) trichloroacetic acid for 2 min, snap-frozen in liquid [N.sub.2], and stored at -80[degrees]C for subsequent Wes analysis [15, 30].
