Description

Tangential section through the anterior half of the cytopharyngeal basket. Drawings and discussion of the basket can be found in a paper by Tucker, J. Cell Science 3: 493-514, 1968. TEM taken on 4/1/69 by R. Allen with Philips 300 operating at 60kV.

Technical Details

Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
