• Background: The histone octamer is composed of a central heterotetramer of two copies of both histones H3 and H4, flanked by two heterodimers of histones H2A and H2B. The octamer assembles when the H3/H4 tetramer complexes with two H2A/H2B dimers. These histones of the histone octamer all contain N-terminal tails that emanate from their central histone folds and are targets for epigenetic modification

• Description: Human recombinant histone tetramer consisting of 2 molecules each of histones H2A (a.a. 1-130(end)), H2B (a.a. 1-126(end)), H3 (a.a. 1-136(end)), and H4 (a.a. 1-103(end)), expressed in an E. coli expression system. Each histone protein has an N-terminal His-tag. Histone H3 has K27C, C97A, and C111A mutations and was alkylated to produce the lysine analog, aminoethylcysteine. GenBank Accession Nos. are NM_033445, NM_003528, NM_003532, and NM_003548, respectively. Global MW = 116 kDa.
