Localization of UNC-87, CeTM and UNC-60B in adult body wall muscle. Wild-type adult nematodes were double-stained with anti-UNC-87 (a,d,g) and anti-actin (b) or anti-UNC-60 (e) or anti-CeTM (h) antibodies. Merged images are shown in c,f,i. Bars, 10 μm. (j) Schematic representation of locations of UNC-87, CeTM and UNC-60B in the thin filaments.
