Proteins & Peptides

Human recombinant histone octamer consisting of 2 molecules each of N-terminal His-tagged histones H2A (a.a. 2-130(end)), H2B (a.a. 2-126(end)), H3 (a.a. 2-137(end)), and H4 (a.a. 2-103(end)), expressed in an E. coli expression system. GenBank Accession Nos. are NM_033445, NM_003528, NM_003532, and NM_003548, respectively. H2B has been biotin-labeled via thiol modification of an additional C-terminal cysteine prior to assembly. Global MW = 117 kDa.

Human core histones (two copies each of H2A, H2B, H3, and H4), purified from cultured HeLa cells. Histones are separated from DNA under high salt conditions.

Human recombinant histone H3 (a.a. 1-136(end)) with K27C, C97A, and C111A mutations, and an N-terminal His-tag, expressed in an E. coli expression system. GenBank Accession No. NM_003532. The protein has been alkylated to produce the lysine analog, aminoethylcysteine. MW = 16 kDa.
