Description

A view of microtubular ribbons in which the periodic structure of the tubulin units can be seen along the length of the microtubules. Short bridges link the microtubules side to side within a ribbon. Many carrier vesicles lie on the same side of the several ribbons exposed in this quick-freeze deep-etch replica. In this image the vesicles appear to lie beneath the ribbons. TEM taken on 5/26/92 by R. Allen with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0.2µm.
