How does TTX work?
Tetrodotoxin (TTX) is a potent toxin that specifically binds to voltage-gated sodium channels. TTX binding physically blocks the flow of sodium ions through the channel, thereby preventing action potential (AP) generation and propagation. Such substitutions confer TTX resistance on a variety of species.
