[Role of non-histone proteins in chromatin solubility].
Treatment of chromatin gel with low ionic strength solution of tRNA has produced the dioxyribonucleoprotein (dnptRNA) in which only part of non-histone proteins was removed without loss of any major histone fraction. The solubility of DNP in the presence of 0.15 M NaCl and 1 to 5 mM MgCl2 was considerably higher than that of initial untreated chromatin. It has been assumed that the solubility of chromatin depended primarily on some non-histone proteins and not on H1 histone.
