A micrograph showing the partially open cytoproct of Colpoda cucullus. The alveoli stop at the edges of the cytoproct and filamentous material (actin?) coats the inside of the single membrane that covers the open cytoproct. TEM taken on 5/3/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. Bar = 0.5?m. The negative was printed to paper and the image was scanned to Photoshop. This digitized image is available for qualitative analysis. A raw, unprocessed, high resolution version of this image (CIL:2858) 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/).
