At the cytopharynx the acidosomes come in contact with the carrier vesicles that are derived from early endosomes. These carrier vesicles bind to the microtubular ribbons as do the acidosomes. The carrier vesicles will bind to the acidosomes and fuse with these acid-containing vesicles. TEM taken on 5/16/73 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 12,750X.
Biological Process: Phagocytosis
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.
