for Recombinant Mononucleosomes H3K27ac - biotin Contents

Recombinant Mononucleosomes H3K27ac - biotinylated (10 µg protein + 10 µg DNA) are supplied in 10 mM Tris-HCl, pH 8.0, 1 mM EDTA, 2 mM DTT and 20% glycerol. Please refer to product insert upon arrival for lot-specific concentration.

for Recombinant Mononucleosomes H3K27ac - biotin 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.

for Recombinant Mononucleosomes H3K27ac - biotin Application Notes

Recombinant Mononucleosomes (H3K27ac) - biotinylated are suitable for use as substrate of enzymatic assay or other biochemical assay.

for Recombinant Mononucleosomes H3K27ac - biotin Protein Details

Recombinant Mononucleosomes H3K27ac - 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), H3.1 that includes amino acids 1-136 (end) (accession number NP_003520.1) with acetylation at lysine 27, and H4 that includes amino acids 1-103 (end) (accession number NP_003539.1). Histone H2A, H2B and H4 were expressed in E. coli cells. H3K27ac was synthesized completely. Histone H3K27ac corresponds to the native histone sequence and does not contain any amino acid substitutions or residue analogs. The molecular weight of histone octamer is ~108 kDa.

Recombinant Mononucleosomes H3K27ac - biotin, DNA gel.

Recombinant Mononucleosomes H3K27ac - biotin, DNA gel.
Mononucleosomes H3K27ac - biotin were run on a 2% agarose gel and stained with ethidium bromide. Lane 1: DNA marker. Lane 2: 601 DNA. Lane 3: Intact mononucleosomes H3K27ac.
Intact mononucleosomes.H3K27ac migrated much higher than free 601 DNA. The agarose gel result shows almost all of 601 DNA wrap histone octamers to form nucleosomes.

Recombinant Mononucleosomes H3K27ac - biotin  tested by Western blot.

Recombinant Mononucleosomes H3K27ac - biotin tested by Western blot
Unmodified nucleosomes (Lane 1) and Recombinant Mononucleosomes (H3K27ac) - biotinylated (Lane 2) were detected with anti-H3K27ac antibody and anti-H4 antibody, respectively. H4 was detected as loading control. Only Recombinant Mononucleosomes (H3K27ac) - biotinylated can be detected by anti-H3K27ac antibody.

for Recombinant Mononucleosomes H3K27ac - biotin Storage

Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
