Description

This image shows a dikinetid which is set in a shallow basin in the cell surface. The pair of basal bodies have a proximal cartwheel and a dense septum (not found in most bbs) just distal to the cartwheel. The terminal plate separates the basal body from the cilium that arises from the distal end of the basal body. TEM taken on 5/31/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The negative was printed to paper and the image was scanned with a flatbed scanner and 0.5µm bar added in Photoshop. This digitized image is available for qualitative analysis. A raw, unprocessed, high resolution version of this image (CIL:2856) is in the library and available for quantitative analysis.Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections were prepared at approximately 75nm thickness. Additional information is available at (http://www5.pbrc.hawaii.edu/allen/).
