Low angle X-ray diffraction studies on stained rat tail tendons. 1978

Low angle X-ray diffraction patterns of rat tail tendons with heavy metal stains added were examined to help clarify the effects of fixation and staining on collagen fibrils. Fixing and staining of rat tail tendon fibers gives an X-ray pattern with an intensified 3.8 nm row and the preservation of most equatorial features found in the native pattern. The presence of the native pattern features suggests the value of fixation in preserving native structure before staining. Staining of rat tail tendon fibers without prior fixation led to the disappearance of the native equatorial features and the appearance of a new broad row line corresponding to a spacing of around 10.0--17.5 nm. This observation suggests that some alteration has taken place in the native structure and may be related to electron microscopic observations of units of 10.0--20.0 nm in collagen fibrils under some disruptive or developmental conditions.
