Abstract
Histones were extracted from pure macronuclei and maoronuolear anlagen and were analyzed by different electrophoretic techniques and by amino acid analysis. Fractionation of the histones on SDS-gels showed that the histone fractions of the macronucleus and the macronuclear anlagen are identical in their molecular weights. Comparison with calf thymus histone fractions showed considerable similarities in the molecular weights. Analysis by polyacrylamide-urea gel electrophoresis and by amino acid analysis showed quantitative differences in some histone fractions between these two types of nuclei.
