Description

The new oral region in the opisthe starts to form as an unorganized field of new basal bodies develops at the equator of the cell surface. At first these do not resemble membranelles although some basal bodies already have short cilia. TEM taken on 8/8/67 by R. Allen with Philips 200 operating at 60kV. Neg. 9,000X. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used 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/).
