Ubiquitous and localized N activity in the larval lymph glands. (A–D) Anti-β-galactosidase staining detects moderate ubiquitous expression of Su(H)-lacZ reporter transgene in lobes of first, second, or third instar larvae. Higher expression is detected in a few scattered cells, presumed crystal cells, in lobes from the third instar animals. (Also see Figure 6).
