Recombinant human histone H2A (HIST1H2AB, H2AC4, accession P04908) expressed in E. coli and purified by FPLC. Histone H2A is one of the four core histone proteins that are present in the nucleosome, the basic repeating unit subunit of chromatin, consisting of 147 base pairs of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3, and H4).
