Longitudinal section of four kinetal rows of Coleps showing transverse sections of cilia and basal bodies. Parasomal sacs/clathrin coated pits penetrate through the plasma membrane into the cytoplasm adjacent to each basal body. An accumulation of early endosome-associated vesicles are near each parasomal sac. Cortical tubular mitochondria are evident. 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 5/23/69 by R. Allen with Philips 300 operating at 60kV. Neg. 6,370X. Bar = 1µm. A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution is available at (CIL:38827) and can be used in quantitative analysis. Additional information is available at (
