Figure 2


Fig. 2. Mlp84B co-localizes with {alpha}-actinin at the Z-disc of sarcomeres in the adult heart. (A) Low-magnification image of a cypher-GFP adult Drosophila heart, encompassing two abdominal segments (A3–A4; note the body wall muscles segmentally arranged on either side of the heart tube). (B) Detail of one segment of a cypher-GFP adult heart. Both the inner spiral and outer longitudinal myofibers are clearly visualized with the Cypher-GFP signal. The scale bar is 40 µm. (C–E) High magnification images of the longitudinal myofibrils stained with anti-{alpha}-actinin (C) and anti-Mlp84B (D) antibodies. Mlp84B forms a doublet on either side of the {alpha}-actinin band (E). The scale bar is 20 µm.
