Recombinant Mononucleosomes H3K14ac (EPL) - biotinylated consist of a 167 bp of 601 DNA with 5' biotin tag and two molecules each of histones H2A that includes amino acids 1-130 (end) (accession number NP_003503.1), H2B that includes amino acids 1-126 (end) (accession number NP_003509.1), H3.2 that includes amino acids 1-136 (end) (accession number NP_066403.2) with acetylation at lysine 14, and H4 that includes amino acids 1-103 (end) (accession number NP_003539.1). All of these histones were expressed in E. coli cells. The molecular weight of histone octamer is ~108 kDa. The recombinant protein is ?95% by SDS-PAGE gel. H3K14ac (Histone H3 acetyl Lys14) protein is generated using expressed protein ligation (EPL) technology. Truncated human Histone H3.2 is produced in E. coli and purified using FPLC. The purified protein is subsequently ligated to a N-terminal histone tail peptide containing acetyl lysine 14 via a native peptide bond.
