OR-Independent Localization of OR83b to OSN Ciliated Dendrites

<p>Immunostaining for OR22a/b (red) and GFP:OR83b (α-GFP, green) in antennal sections of control heterozygous (<i>Or22a/b^Δhalo/+;Or22a-Gal4/UAS-GFP:Or83b</i>, top panels) and homozygous (<i>Or22a/b^Δhalo/Or22a/b^Δhalo;Or22a-Gal4/UAS-GFP:Or83b,</i> bottom panels) <i>Or22a/b</i> null-mutant animals. Images of control and mutant samples were taken at identical confocal settings to permit comparison of signal intensities.
