Tetrahymena

An early-dividing wild-type cell stained with a monoclonal antibody (4F9) that recognizes ciliary basal bodies. The basal bodies of the ciliary rows and of the old (anterior) and new (equitorial) oral apparatuses are prominent.

An early-dividing wild-type cell double-stained with a monoclonal antibody(4F9) that recognizes ciliary basal bodies plys another monoclonal antibody (8H3) that recognizes the region immediatley posterior ro the division furrow.

A non-dividing wild-type cell stained with a monoclonal antibody (15d#) that recognizes microtubules. The basal bodies plus the accessory tranverse, postciliary, and longitudinal microtubule bands are visible.

A non-dividing cell stained with a monoclonal antibody (6D3) that recognizes the kinetodesmal fibers (ciliary rootlets).

A conjugating (mating) cell stained with a monoclonal antibody (4F9) that recognizes ciliary basal bodies plus another monoclonal antibody (6D3) that recognizes nuclei. The macronuclei of the two cells are visible, as well as micronuclei in the elongated "crescent" stage of meiotic prophase.

A non-dividing cell stained with a monoclonal antibody (1B1) that recognizes a component of the epiplasmic (membrane-skletal) layer, which immediately underlies the plasma membranes. The dark (unstained) areas correspond to the locations of the basal bodies and of the longitudinal microtubule band.

Am early-dividing disorganizedA1 (disA1) mutant cell stained with a monoclonal antibody (4F9) that recognizes ciliary basal bodies. The basal bodies of the disorganized ciliary rows and of the normal old (anterior) and new equatorial) oral apparatuses are prominent.
