Description

A view of the rough endoplasmic reticulum of Tetrahymena that sometimes forms large stacks or concentric circles from which other organelles are excluded. Peroxisomes lie nearby. EM taken on 6/21/67 by R. Allen with RCA EMU3F operating at 50kV. Neg. 18,800X. Bar = 0.5µm. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. An unprocessed, high resolution version of this image (CIL:34617) is in the library and available for quantitative analysis.

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/).
