Fig. 2. Brightfield (left) and fluorescence (right) micrographs showing FL
accumulation in Acheta Malpighian tubules. In some cases,
fluorescence was stronger in the lumen (A), while in others it was more
generally dispersed through lumen and cell (B). In (C) FL is present in both
the Malpighian tubule (right) and the larger ureter (left) that connects
Malpighian tubules to intestine.
