pre-autophagosomal structure membrane
The nascent phagosome membrane has a dense coat of acidosomes docked at its cytosolic surface well before the nascent vacuole pinches off the cytopharynx. This micrograph is a quick-freeze deep-etch i...

pre-autophagosomal structure membrane
Monoclonal antibody for antigen B2 (called mAb PC-1 in Fok et al., Eur. J. Cell Biol. 40:1-8, 1986) is located on the cytopharynx and along the cytopharyngeal ribbons. It can be seen here on the DV-I ...

early phagosome
Immunogold label specific for Q2 antigen on discoidal vesicles. The same mAb used in CIL:36721 heavily labels discoidal vesicles and less heavily the cytopharyngeal membrane. A few gold particles are ...
