A view of the ER on which IMPs are organized into lines, arcs, and circles indicating organization of proteins within the ER membrane and possibly peripheral proteins attached to its cytosolic surface...

Human melanoma cell undergoing cell division. The chromosomes (blue) have separated and the two daughter cells have almost split apart - only a small bridge of cytoplasm remains. The green staining la...

COS 7 cell expressing Organelle LightsTM ER-GFP (Invitrogen) consiting of the signal sequence of the ER protein calreticulin and a KDEL retention sequence. Images were collected with a 63X 1.4 NA Pla...

A 3-D model of the three trans-Golgi cisternae and associating ER in a portion of the Golgi stack. The modeled cisternae (in cis-to-trans order) are colored rose (C5), gold (C6) and red (C7). The asso...

Transmission electron micrograph showing the extensive accumulation of darkly stained heterochromatin at the nuclear periphery typical of many differentiated cells. Heterochromatin is excluded from re...
