X-ray analysis shows that the nucleated erythrocytes of the amphibian Necturus maculosus (Mud Puppy) contains more ordered chromatin than most nuclei. Here, chromatin fibers were isolated from N. mac...

The protein MeCP2 binds to symmetrically methylated CpG dinucleotides and is thought to transmit the (generally) repressive signals encoded in DNA methylation patterns. Mutations in MeCP2 lead to Rett...

Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...

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 phosp...

Upon electron bombardment, some elements, such as P, show an electron energy loss profile with a peak at a specific energy loss value. By collecting a series of images of a field at different energy l...

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...
