The image shows a portion of a slice through a 3D tomographic reconstruction of a mouse adenocarcinoma cell based on x-ray microscopy. Live cells were cryofixed by plunge freezing in liquid ethane an...

Endoplasmic reticulum (ER) domains in 3D in a wild type S. cerevisiae cell (wt = BY4742) with a 665-nm bud. Domains are color coded as follows: Golgi (purple), and vesicles (30 nm is shown in pink, a...

Low-power micrograph illustrating the general preservation of the cytoplasm in a Micrasterias cell stabilized by ultrarapid freezing. The large, sheetlike membranes of the rough endoplasmic reticulum...

Micrograph illustrating the general preservation of the cytoplasm in a Micrasterias cell stabilized by ultrarapid freezing. E-face of RER membranes depicting several spiral imprints of polysomes. Th...

Micrograph illustrating the Golgi apparatus and rough endoplasmic reticulum (RER) cell stabilized by ultrarapid freezing. Note the relationship of the RER membrane to the Golgi complex. Technical d...

An animation that takes the viewer inside a mammalian cell where one can see the nucleus and its characteristic envelope connected to the endoplasmic reticulum. The movie starts with a brief video cli...
