Fig. 1. Indirect immunofluorescence of choline acetyltransferase-related molecules analyzed by confocal laser scanning microscopy. Mating-competent mt I cell (Ai) and control (Aii). Mating-competent mt II cell (Bi) and control (Bii). Non-mating-competent cell (Ci) and control (Cii). Sections of an immature cell from the inside (D) to the surface (I). Scale bars, 20µm.

Fig. 2. Choline acetyltransferase activity, revealed as a dark precipitate, produced using the method of Burt (Burt, 1970). Mating-competent mt I cell (Ai) and control (Aii). Mating-competent mt II cell (Bi) and control (Bii). Immature cell (Ci) and control (Cii). Non-mating-competent cell (D). The control for the non-mating-competent cell is not shown because the complete absence of staining made it impossible to photograph. Scale bars, 20µm.

Fig. 3. Choline acetyltransferase (ChAT)-like molecules examined by immunoblot. Lane A, molecular mass standard marker; lane B, ChAT from human placenta; lanes C and D, membrane lysates from mating-competent mt I and mt II cells, respectively; lanes E and F, membrane lysates from non-mating-competent and immature cells, respectively; lanes G and H, cytoplasmic fractions from mating-competent mt I and mt II cells, respectively; lanes I and L, cytoplasmic fractions from non-mating-competent and immature cells, respectively.
