Quick-freeze deep-etch image of a crystal. The contents of the crystal have condensed into paracrystalline planes that break into angular chunks when fractured. A portion of the P-fracture face of the...

QF-DE of a crystal whose P-fracture face shows many IMPs similar to the P-face of an acidosome lying nearby and trichocyst as well as trichocyst precursor vesicles. TEM taken by C. Schroeder on 6/3/8...

A population of CHO cells constitutively overexpressing a clone of human IgG2/kappa. CHO cells are regarded as the workhorse of recombinant protein expression and biopharmaceutical production. Under c...

Paramecium also contains many crystals in older cultures. This micrograph is of a crystal taken from a cell in stationary phase (day 8 post-inoculation). Crystals are enclosed by a membrane and contai...

This micrograph shows a crystal surrounded with secondary lysosomes. This was taken from a cell returned to growth medium following starvation for several days (0 day of rejuvenation). This could repr...
