[Anomalous mobility of histone dimer H3 in gel-filtration on Acrylex P-60]

Under gel-filtration on acrylex P-60 the total histone of the calf thymus is divided into 5 fractions - [H1], [H2A], [H2A, H3+(H3)2, H2B], [H2B] and [H4]. It is established that the yield volume of histone H3 dimer formed due to the intermolecular disulphide bond is the same as that of the monomeric form. It may be explained by a compact structure of the histone H3 dimer.
