A high resolution of an oblique section of the Coleps contractile vacuole pore revealing the supporting microtubules and adjacent fibrous layer. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. TEM taken on 3/4/69 by R. Allen with Philips 300. Neg. 25,100X. The raw film was scanned with an Epson Perfection V750 Pro. This high resolution image is suitable for quantitative analysis Additional information available at (
