Fig. 2. SDS-PAGE electrophoresis profiles of salt-soluble proteins, water-soluble proteins and insoluble proteins fractions of different parts of bullfrog.

Lanes 1–3 represent salt-soluble proteins in the fore-chest, thigh, and calf, respectively. Lanes 4–6 represent water-soluble proteins in the fore-chest, thigh, and calf, respectively, and lanes 7–9 represent insoluble proteins in the fore-chest, thigh, and calf, respectively. SDS-PAGE, sodium dodecylsulphfate-polyacrylamide gel electrophoresis.
