[Surface charge of isolated hepatocyte nuclei during change in their functional activity]

We have measured densities of surface charge of hepatocyte nuclei during hydrocortisone induction and activation induced with amino acids mixture. The value of single nucleus charge, calculated from the value of charge density, changes more during both forms of induction, that the value of the electrokinetic potential. Thus the former better characteristics the electrokinetic properties of nuclei during their functional swelling.
