Figure 1.

SDS-PAGE analysis of the supernatants obtained after treating intact cells with trypsin; see materials and methods for details. The gel shows the results from cells treated with trypsin, cells treated with trypsin beads and a control sample ("untreated") where no trypsin was added. Samples sizes represent approximately the same amount of cells in all lanes.
