A collecting canal of the contractile vacuole surrounded by smooth spongiome remnants and decorated tubules of the CVC. Microtubules bordering the flattened collecting canal are labeled with immunogold when thin frozen sections of the CVC are exposed by the indirect immunogold technique to show anti-b-tubulin. These microtubules have their origin at the cytosolic side of the CV pore. TEM taken on 2/25/94 by R. Allen with Zeiss 10A operating at 80kV. Neg. 9,780X. 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:13124) 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 prepared at approximately 75nm thickness.
