Human recombinant histone tetramerconsisting of 2 molecules each ofhistones H3 (a.a. 2-136(end)) and H4(a.a. 2-103(end)), expressed in an E. coliexpression system. Histone H3 hasK27C, C97A, and C111A mutations andwas alkylated to produce the lysineanalog, trimethyl aminoethylcysteine.GenBank Accession Nos. NM_003532,and NM_003548, respectively. Eachhistone protein has an N-terminal Histag.Global MW = 57 kDa.
