Figure 10
A small-angle X-ray diffraction pattern from a glycerinated ABRM in the rigor state which had been recorded on X-ray film before imaging plates became available. The ABRM was glycerinated by the method of Baguet (1973BB3), and the X-ray pattern was taken by a rotating-anode microfocusing X-ray generator operated at 40 kV and 15 mA (nominal focal size 0.1 mm × 0.1 mm) and a mirror-monochromator point-focusing camera with a camera length of 0.25 m. The exposure time was 75 h. The pattern shows a ladder-like appearence of the layer-line reflections from the thin filaments involving 51 and 59 Å layer lines, and three layer lines under the 59 Å layer line, similar to the rigor patterns from striated muscles (Wakabayashi & Amemiya, 1991BB22).
