| Cat.No.: | NUC-0130 |
| Product Name: | Recombinant Mononucleosomes H3K14ac (EPL) |
| Product Overview: | 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. |
| Background: | In vivo, histones are wrapped around by DNA in chromatin. Therefore, nucleosomes are more physiologically relevant substrates than histones and histone-derived peptides for in vitro studies. More importantly, some histone methyltransferases are significantly more active, as well as specific, when using nucleosomal substrates in HMT assays, such as DOT1L and NSD family enzymes. Nucleosomes are also widely used in histone methyltransferase screening assays to identify small molecular inhibitors for drug discovery. |
| Applications: | Suitable for use in the study of enzyme kinetics, inhibitor screening, and selectivity profiling. |
