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...

Visualization of clathrin coated pit dynamics. Total internal reflection fluorescencec microscopy (TIRF-FM) was performed on live human retinal pigment epithelial (RPE) cells stably expressing 'clathr...

Human retinal pigmented epithelial (RPE) cells labeled for clathrin-coated pits (green), focal adhesions (red) and nuclei (blue). RPE cells stabily expressing 'clathrin light chain a' tagged with EGFP...

Cross fracture of cilia of the quadrulus. The basal body/cilium complexes are a little less tightly packed than in the peniculus. There are four or five rows of parasomal sacs interspersed with basal...

Image of the pellicle of Opercularia coarctata. Indentations of the plasma membrane penetrate the alveolar membranes end as coated pits. These pits are also known as pellicular pores are homologous to...

High resolution of the layer of contractile myonemes in Opercularia coarctata that covers most of the cytosolic side of the pellicle. Pellicular pores (the clathrin coated pits of ciliates) penetrate ...

The layer of contractile myonemes in Opercularia coarctata that covers most of the cytosolic side of the pellicle. Pellicular pores (the clathrin coated pits of ciliates) penetrate through this sheet....

The cortex of Paramecium consists of a plasma membrane and alveolar sacs, with their inner and outer alveolar membranes that limit the area in which endocytosis can easily occur to only the parasomal ...

Vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch preparation. Preendosomal ve...
