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.

Chicken erythrocyte nuclei were allowed to disperse in low salt, centrifuged through formaldehyde onto an EM grid, stained with uranyl acetate, and examined with the Madison 1MeV TEM at 40 KX in darkf...

Sarcolemma of skeletal muscle prepared by a quick-freeze deep-etch method also shows the basement membrane (lamina externa, labeled here as the basal lamina) associated with the muscle fiber. This me...

Meiotic newt oocyte nuclei were allowed to disperse in 30 mM KCl/NaCl, centrifuged through 2% formaldehyde onto an EM grid, stained with uranyl acetate, and critical point dried. Grids were examined ...
