All strains were grown at 22°C. L4/young adults were analyzed using fluorescence microscopy for autofluorescent, acridine orange, and Nile Red signals in intestinal cells using a standard rhodamine filter. Animals were scored for the number of fluorescent organelles present within the intestine. +++, ++, +, and − correspond to >500, 51–500, 1–50, and 0 organelles, respectively. Values in parentheses are the number of animals scored.
a pgp-2 point mutants contained weakly autofluorescent compartments compared with wild type.
b pgp-2 point mutants contained weakly stained Nile Red–stained compartments compared with wild type.
