TTX was purchased from Tocris Bioscience (Ellisville, MO) and veratridine was from Sigma-Aldrich (St.
influx produced by pyrethroids were all lower than that of 10 [micro]M veratridine (Figure 1A), a plant-derived sodium channel neurotoxin site 2 agonist.
i] induced by acetylcholine (ACh), veratridine (Ver) and/or 56 mM [K.
Reagents were obtained from the following sources: Eagle's minimum essential medium (MEM) and new born calf serum from Gibco (USA); collagenase from Nitta Zerachin (Osaka, Japan); acetylcholine and veratridine from Sigma (St.
In response to stimulation by veratridine, a secretagogue (a substance that induces secretion) that targets voltage-gated [Na.
The present study further characterizes these major processes of cholinergic function, by analyzing the time-course of ACh release and Ch uptake and by comparing the effect of two secretagogues, KCl and veratridine, in pinched-off nerve terminals (synaptosomes) from cuttlefish optic lobes.
