title: A new preparative method for microspectrophotometric DNA-measurement in megakaryocytes, revealing a significant group of cells with a DNA content of 64 N.
abstract: Microspectrophotometric investigations of Feulgen-stained rat bone marrow megakaryocytes, comparing the traditional smear method and a new 1 G sedimentation and 40 degrees C evaporation (S. E.) method, have shown that the latter reveals a significant group of megakaryocytes (ca. 30 percent) with a DNA content of 64 N. This group is totally absent when the smear method is used.
