Figure 1. SDS-PAGE of parotoid gland secretions from Bufo mauritanicus
and Bufo calamita. The
Laemmli separating gel was visualized by Coomassie Blue staining. Lane 1: molecular
mass markers. Lane 2: B. mauritanicus freeze-dried secretion (100 microg).
N-terminal amino acid sequences were obtained from bands at the positions marked
A, B and C. Lane 3: B. calamita freeze-dried secretion (100 microg).
N-terminal amino acid sequences were obtained from the diffuse major band marked
