Characterization of a polyclonal antibody that is highly selective for the d-isoAsp-25 variant of mammalian histone H2B

Approximately 12% of histone H2B molecules in mammalian brain contain a modification wherein Asp25 is present as the d-enantiomer, and is mostly linked to Gly26 via the side-chain carboxyl. Here we (1) demonstrate the high specificity of a polyclonal antibody to this modification, and (2) use this A...

Sumario:Approximately 12% of histone H2B molecules in mammalian brain contain a modification wherein Asp25 is present as the d-enantiomer, and is mostly linked to Gly26 via the side-chain carboxyl. Here we (1) demonstrate the high specificity of a polyclonal antibody to this modification, and (2) use this Ab to demonstrate that this modification is enriched in brain relative to liver, thymus, and HeLa cells.
