Figure 5From: The Oct1 homolog Nubbin is a repressor of NF-κB-dependent immune gene expression that increases the tolerance to gut microbiotaLocalization of Nub protein in immunocompetent tissues of flies. (A,B) Immunostaining of Nub in frozen cryostat sections of uninfected OrR flies using a peptide-specific antibody directed against a common epitope of Nub-PB and Nub-PD protein. Nuclei stained with 4′-6-diamidino-2-phenylindole (DAPI) (A′-B′). Cryostat sections (20 μm thick) of adults showing nuclear (arrows) and cytoplasmic and staining of Nub in fat body tissue (A,A′) and in cross-sections of midgut (B,B′). Scale bars, 100 μm.Back to article page
