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...

Transmission electron micrograph of a thin section of a capillary from the ventricular myocardium of the rat showing part of a reticulocyte (immature erythrocyte) in the lumen of the capillary. The re...

This section is cut at a level where the macronucleus is folded so it appears to be in 2 parts and where the micronucleus is visible. Contractile vacuole, perioral kinetids, and the peristome is evide...

The macronucleus is the largest organelle in the P. multimicronucleatum cell and can measure 35µm long by 12µm wide. A small fraction of a macronucleus is seen in this micrograph. The chromatin appe...

Vorticella convallaria fixed for EM and buffered in cacodylate. The rough ER is not vesiculated as it is in collidine buffered fixatives but appears as sheets from which Golgi dictyosomes arise. A foo...

Single slice confocal images representing one optical slice of a cell stained for the Human Protein Atlas (HPA) HPA006427 antibodies (shown in green). HPA006427 is a polycolonal anti-PLIN3 antibody t...

Single slice confocal images representing one optical slice of a cell stained for the Human Protein Atlas (HPA) antibody HPA001842 (shown in green). HPA001842 is a polyclonal anti-PTK2 antibody that l...

Detail of cytopharyngeal vesicles. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0.5µm. A print of the negative was scanned and processed in Photoshop. Th...

The transition from 3 to 2 rows of cilia can be seen in this view of the AZM. TEM taken on 7/24/67 by R. Allen with Philips 200 operating at 60kV. Neg. 1,370X. Bar = 5µm. Standard glutaraldehyde fix...

High resolution view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of ...
