Other defecation mutants also display reduced uptake of C₁-BODIPY 500/510 C₁₂.

<p>A. Confocal fluorescence micrographs of worms fed the fluorescently labelled fatty acid derivative C₁-BODIPY 500/510 C₁₂. The arrows indicate the lumens of the intestine. In all panels, the anterior part of the intestine is up and (in most) slightly to the right. Scale bars are 40 μm. B. Quantification of the uptake of the dye into the cytoplasm of intestinal cells (in arbitrary units). Error bars indicate standard errors of the means. **** indicates significant difference in the means determined by one-way ANOVA and Dunnett's multiple comparisons test (σ = 0.05).
