Figure 1-A. Staining of Tetrahymena thermophila incubated with 5545 preimmune serum.  A light micrograph (top) and a fluorescence micrograph(bottom) is shown for each cell.  Total magnification = 1000X.

Figure 1-B.  Staining of non-adapted Tetrahymena thermophila with 5545 anti-lysozyme antibody.  A light micrograph (top) and a fluorescence micrograph (bottom) is shown for each cell.  Total magnification = 1000X.

Figure 1-C.  Staining of lysozyme-adapted Tetrahymena thermophila with 5545 anti-lysozyme antibody.  A light micrograph (top) and a fluorescence micrograph (bottom) is shown for each cell.  Total magnification = 1000X.
