Fig. 7. Electron microscopic observation on ultrathin sections of ABRM reacted with
anti-twitchin D2 peptide antibody in active contraction, catch and relaxation
stages. Longitudinal (A,C,E,G) and cross-sectional (B,D,F,H) views for ABRM in
active contraction (A,B), ABRM in catch (C,D), ABRM in relaxation (E,F) and
ABRM without the antibody (control) (G,H). Bars, 200 nm (A–F), 500 nm
(G), 100 nm (H).
