[Heterogeneity of histone H1 in cells with blocked genome]

Using polyacrylamide gel electrophoresis, the composition of cationic chromosomal proteins of the cells with completely blocked genome (crayfish, triton and frog spermatozoa, bird erythrocytes, rabbit and cow neutrophils) and homologous somatic cells with matrix-active genome was studied. It was shown that the most common feature of the composition of these cationic chromosomal proteins is the presence of several subfractions of histone H1. This is probably due to the necessity of total condensation of chromosomal fibrills.
