Characterization of Ldh expression in the intestine and Malpighian tubules.

The Ldh expression pattern in the intestine and Malphigian tubules of L3 larvae was examined using Ldh-GFP^Genomic, Ldh-GFP^enhancer, and an aLdh antibody. (A-L) Representative confocal images of Ldh expression and DAPI staining in (A-F) the midgut and (G-L) the Malphigian tubules. Note that Ldh is expressed at significantly higher levels in (A,C,E) a subset of small cells of the AMP clusters (denoted with arrowheads in (A-F)) and (G,I,K) the stellate cells of the Malpighian tubules. The scale bar in all images represents 40 μM.
