Fig. 7
Slow and fast muscle fibers can be unambiguously distinguished by immunolabeling. A transverse section of a 32 d zebrafish was doubly immunolabeled with the S58 antibody and the 12/101 antibody (A-C). (A) S58 (green) recognizes only the slow muscle fibers. Some non-specific fluorescence is present within blood vessels in all muscle regions (e.g. arrows). (B) 12/101 (red) recognizes fast and intermediate, but not slow muscle fibers. (C) 12/101 (red) and S58 (green) label mutually exclusive muscle fibers. In these transverse sections, dorsal is up. Scale bar, 100 μm. |
