Figure 2.

Two-dimensional SDS-PAGE of lamellar body proteins. Isolated lamellar bodies (500 μg of protein) were analyzed by 2-D polyacrylamide gel electrophoresis. Protein spots were visualized by staining with Coomassie Brilliant Blue G-250. Isoelectric points (pI) and molecular masses are shown on the top and the left of the panel, respectively.
