Fig. 5. Expression of PBP1 and GOBP2 in sections of male and female antennae. (A–F) Male (m; A,B) and female (f; C,F) antennae were sectioned and probed with antisense RNA encoding PBP1Msex (P) or GOBP2Msex (G2). Insert diagrams indicate the positions and orientations of sections. (G–H) Comparison of the vertical distribution of PBP1 mRNA (G, in situ hybridization using GOBP2Msex probe) and PBP1 protein (H, immunocytochemistry using PBP1Msex antiserum) in the female antenna. (I) Control in situ hybridization. Tissue was from pharate adult animals. Size bar in I, 100 µm (A–F,I); in G, 25 µm (G,H).
