The linkage complex consists of a spindle shaped mid piece bordered, in one plane, by several rails that have subunits that pass through the ER membrane. Thin filaments splay out from both tips of the...

A cross-section and tangential views of three other linkage complexes. The mid piece sits in an indentation of the ER membrane on a bed of 5 slats that pass through the membrane. Rails affix the ER me...

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...

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...
