Follicle of the giant silkmoth Antheraea polyphemus.
The cortical region of the developing follicle of the giant silkmoth Antheraea polyphemus stained with a monoclonal antibody against cytoskeletal actin. The primary antibody was visualized using biotin-XX goat anti–mouse IgG antibody (Cat. No. B2763), followed by incubation with Texas Red® streptavidin (Cat. No. S872). The orange-to-pink colors in this confocal laser-scanning micrograph show the distribution of cytoskeletal actin in the oocyte cortex and follicle cell cytoplasm. The blue color can be attributed to autofluorescence. The image was contributed by Ivo Sauman, Wesleyan University.
