chicken erythrocyte nuclei were allowed to decondense in a low salt high pH buffer, fixed with HCOH, centrifuged onto a carbon coated EM grid, and stained with uranyl acetate. (Spreading technique of ...

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...
