Disulphide bridging of calf thymus histone H3 by 5,5'-dithiobis(2-nitrobenzoic acid)

Electrophoretic analysis of the reaction products of calf thymus histone H3 with 5,5'-dithiobis(2-nitrobenzoic acid), under mild conditions, shows that different oxidized forms of this histone are originated by disulphide interchange. One of the species detected is the intramolecular oxidized monomer of histone H3.
