One parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that penetrates into the cytosol past the alveolus. Most sacs end ...

High resolution micrograph of the cortex of Tetrahymena. One parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that pene...

A high resolution 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...

Electron micrograph of PC12 cells transfected with AP-3 siRNA. PC12 cells were plated onto aclar film discs (Pella) coated with poly-L-lysine, transfected twice with 50 nM AP-3delta1 siRNA and fixed w...

Wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) colocalizes primarily at the Golgi (Giantin) (red) with Helix Pomatia Lectin (HPL) (green) in unstimulated HeLa cells. HPL binds various glycans but the Tn ant...

Constitutively active mutant Arf1-GFP (Arf1(Q71L)-GFP) (gray) colocalizes primarily at the Golgi (Giantin) (red) with Helix Pomatia Lectin (HPL) (green) in unstimulated HeLa cells. HPL binds various g...
