Description

Polykinetids of one membranelle of the buccal cavity, probably membranelle 1. Accessory microtubules arise from the row of basal bodies on one side. Parasomal sacs are not seen associated with this membranelle although several early endosomes are seen at one end of the membranelle. TEM taken on 8/22/67 by R. Allen with Philips 200 operating at 60kV. Neg. 12,400X. Bar = 0.5µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
