Rabbit psoas skeletal muscle fibers were held at constant length and rigor induced by immersion in glycerol. The fibers were fixed in buffered glutaraldehyde, treated with tannic acid and quick-froze...

The plastids of plants germinated in the dark are termed etioplasts and possess quasi-crystalline structures termed prolammelar bodies that contain the phospholipid materials and chlorophyll precursor...

Synapse formation in cultured hippocampal neurons after 7 days in vitro. Cells were immunostained for MAP2, a microtubule associated protein localized to dendrites but not axons (green), and synapsin...

Cross section of basket from Nassula aurea (C.N.R.S., Yvette, France) through its “waist”. Rods, rod lamellae, and the surrounding sheath are seen. Cytopharyngeal vesicles fill the basket lumen an...

Detail of cytopharyngeal basket from Nassula aurea. Microtubules make up the rods, rod lamellae and sheath. TEM taken on 3/2/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 19,500X. Bar = 0....

An image that shows the extensive layer of cortical microtubules which lie under the pellicle and many other microtubules and mitochondria that form a mass in the cytosol. Standard glutaraldehyde fixa...

The cytostome of Opercularia divides the peristome from the cytopharynx. The cytopharynx starts where the alveoli end in the oral region. TEM taken on 6/13/69 by R. Allen with Philips 300 operating at...

In this study, we developed an electron microscopy method, called CryoChem, to optimally preserve the morphology of genetically labeled tissues. This method also allows us to perform 3D correlated lig...
