High resolution image of cross sections of basal bodies at the level of their attachments to the kinetodesmal fiber, the anterior basal body is attached by a thin bridge. The proximal ends of one postciliary microtubular ribbon and a transverse microtubular ribbon are next to the pair of basal bodies. Infraciliary lattice, post of lattice, and trichocyst tip are seen. TEM taken on 2/21/69 by R. Allen with Philips 300 operating at 60kV. Neg. 47,100X.The raw film was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.
