Fig. 3. Immunolocalisation of Mvl in the larval brain (A–C) and testis (D–F). (A) Reactivity in a subset of neurons within the larval brain. (B) Higher magnification of these neurons (arrows) shows staining associated with a sub-cellular compartment. (C) Immuno-blocking with Mvl peptides. (D) Reactivity within the larval gonad, and also staining associated with cells of the fat body (arrow). (E) Higher magnification show Mvl-positive staining associated with a subcellular structure within the cells of the testis (arrow). (F) Immuno-blocking with Mvl peptides. Scale bars, 200 µm (A,C,D,F); 100 µm (B,E).
