Description

In the contact area between two conjugating cells the tips of the ridges all fuse forming openings between the two cells. TEM taken on 3/4/80 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 8,500X. Bar = 0.5µm.

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. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis.
