Typical images of the synthetic thick filament (myosin-paramyosin core complex). (A) Imaging plate record of the thick filaments with gold particles attached to the myosin heads, taken with a magnification of ×10,000. (Bar = 500 nm.) (B) Conventional electron micrograph of the filaments after negative staining with uranyl acetate and rotary shadowing with platinum (thickness, 2 nm). (Bar = 100 nm.) (C) Enlarged imaging plate record showing part of a thick filament with gold particles on it. (Bar = 100 nm.) Arrows in B and C indicate gold particles.
