FIG. 2

Computer averaged images of 28 α2M molecules shown to interconvert between the lip (A) and the padlock (B) views obtained from the specimen tilted ±22.5°. The major axis of the tilted images are 10–15% shorter than the average images in Fig. 3. The shortening of this dimension resulted from the fact that the major axis of the molecule was not exactly parallel to the tilt axis of the stage. The untilted particles in this data set had a major axis of 200 Å. The scale bar corresponds to 100 Å.
