Figure 4From: Identification of a novel Drosophila gene, beltless, using injectable embryonic and adult RNA interference (RNAi)Adult blt RNAi, triggered by injections of blt dsRNA into the abdomen of adult female flies. RT-PCR assay was performed 4.5 days after injections. Lane 1: control, lane 2: blt dsRNA (100 ng/μl), lane 3: blt dsRNA 10 ng/μl. Upper bands, blt mRNA; lower bands, ribosomal rp46 mRNA. Note the absence of blt mRNA in lanes 2 and 3.Back to article page
