Figure 2

Chick biventer cervicis preparations in Krebs (control, (a)), or incubated with 10 μg/mL of BmjeTX-I (b) and with 10 μg/mL of BmjeTX-II (c) toxins isolated from B. marajoensis crude venom. Notice, in (b) and (c), the irreversible neuromuscular blockade induced after  min and  min ( from Krebs) of toxins () addition, respectively. ACh and KCl addition; : washes ( for each treatment).
