Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas showing endoplasmic reticulum at left and Golgi apparatus at right. Image made available by James...

The cytoplasm of P. multimicronucleatum like all other cells contains a large number of organelles that are membrane bound. Membranes are used to compartmentalize and isolate metabolic and enzymatic p...

Single slice confocal images representing one optical slice of a cell stained for the Human Protein Atlas (HPA) antibody HPA038474 (shown in green). HPA038474 is a polyclonal Anti-RCN1 antibody that ...

Single slice confocal images representing one optical slice of a cell stained for the Human Protein Atlas (HPA) antibody HPA030827 (shown in green). HPA030827 is a polyclonal anti-LRRC59 antibody tha...

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

Figure 191 from Chapter 5 (Endoplasmic Reticulum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A thin section through frog sartorius muscle shows the organization of the sarcoplasmic reticulum in am...

V. convallaria preserved in collidine buffered fixative (not cacodylate) has a less dense cytoplasm in which oranelles are easier to recognize. The rough ER has vesiculated but this vesiculation enhan...

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...

Endoplasmic reticulum, mitochondria with their tubular cristae and a Golgi stack. Ribosomes are scattered in the cytosol. TEM taken on 3/13/69 by R. Allen with Philips 300 operating at 60kV. Neg. 20,5...

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...
