A drop of a preparation of chicken erythrocyte nuclei was exposed to low ionic strength and centrifuged onto a formvar-carbon film, fixed with paraformaldehyde and negatively stained with sodium phosphotungstate. Images were recorded at 40KX and accelerating voltage of 1MeV at the University of Wisconsin HVEM facility.This image was taken with a specimen tilt of 45 degrees. A grouped image of the same field at a 55 degree tilt provides an oblique stereo view of a tangle of chromatin fibers extending from the dispersed nucleus.
