A high resolution image of a dikinetid of Euplotes shows the transverse microtubular ribbon as well as a postciliary ribbon extending from the posterior basal body. Vesicles containing electron opaque bodies are typically found next to basal bodies. A peroxisome is also present. In this section a pattern of cross-hatched microtubules lies immediately under the cell surface membranes. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 8/3/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. The raw negative was scanned with an Epson Perfection V750 Pro. This image is best used for quantitative analysis.
