Fragile X chromosome made visible by atomic force microscopy (AFM). The arrow indicates the fragile site. Additional AFM chromosome images are available as CIL 38987, 39000, and 38915.

Scanning probe/atomic force microscope image of human chromosome 1. Additional scanning probe chromosome images are available as CIL 38987, 39000, and 39013.

Scanning probe/Atomic Force Microscope image (contact mode) of a molecule of the muscle protein myosin (green on yellow background). The two heads and tail of the molecule are clearly resolved.

Scanning probe/atomic force microscope image of human chromosomes in a metaphase spread. Additional scanning probe images of chromosomes are available as CIL 39000, 38915, and 39013.

Rabbit psoas skeletal muscle fibers were held at constant length and rigor induced by immersion in glycerol. The fibers were quick-frozen by contact with a liquid helium- cooled copper block in a Heu...

Quick-freeze deep-etch image of a cytosolic region where trichocysts are developing. Vesicles, even small ones, contain contents that are compacting into paracrystalline form. These vesicles seem to h...

Purified rabbit skeletal muscle myosin in 0.6M KCl was adsorbed onto mica flakes, quick frozen by contact with a liquid helium-cooled copper block in a Heuser-type cryopress (Heuser JE, J. Mol.Biol. 1...
