This view shows a transverse ridge cut with its sloping side lying tangentially in the section plane. The granulo-fibrillar filled peaks are prominent. Striated bands appear sectioned closer to their mid-sections, probably in areas of filament overlap. The outer alveolar membrane is not usually continuous with the inner alveolar membrane at the tips of the ridges. TEM taken on 11/11/70 by R. Allen with Hitachi HU11A operating at 60kV. Neg. 37,700X.
Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness. The raw negative was scanned with an Epson Perfection V750 Pro and this high resolution image is best used for quantitative analysis.
