FIG. 2.

Immunolabeling of S-layer proteins in capsulated CAF10 bacteria. Thin sections were incubated with anti-EA1 (A) or anti-Sap (B) antibodies and then with 10-nm gold-conjugated anti-rabbit antibodies. The capsule is visible in these micrographs but was only weakly stained with the protocol used. Bar, 200 nm.
