Abstract
Tubulin, actin, and myosin have been localized in isolated demembranated ciliated cells from quail oviduct by immunocytochemistry in both light and electron microscopy by using purified antibodies. The peripheral doublets and the central tubules are stained by the antitubulin whereas the kinetosomes are poorly stained. Actin antibodies clearly stain the axonemes, but only on the proximal-half portion, whereas myosin antibodies stain a small area of the axonemes just above the ciliary neck region.
