Phagosome acidification and neutralization visualized using FITC-yeast. Amoebae of Dictyostelium discoideum were fed living budding yeast (S. cerevisiae strain TH2-1B) that had been labeled with fluor...

Monoclonal antibody, E30-2-1, was raised to antigen D6 that specifically labels acidosomes and DV-II. There was no label on the nascent vacuole membrane or ciliary membranes. This cell had been incuba...

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 ...

The nascent digestive vacuole forms as the membrane of flattened vesicles fuse with the single membrane of the cytopharynx between the lamellae (2 microtubules forming a lamella) that are connected al...

Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...

Localization on the cell surface of Alexa Fluor-488-α factor (left, green in merge) and Sla1-RFP (center; red in merge). Within each white box, α-factor spots first appear and are subsequently joine...

Cultured retinal pigment epithelial cells immunofluorescently labeled for adaptor protein-2 (AP2) (green) and nucleus (blue). The cells were fixed in 2% PFA and 0.5% Triton X-100 for 2 minutes follow...
