Testing Data
(Recombinant Mononucleosomes (H3.1) DNA agarose gel Mononucleosomes (H3.1) were run on an agarose gel and stained with ethidium bromide. Lane 1: DNA Marker. Lane 2: 601 DNA which was used for assembly of nucleosomes. Lane 3: Intact nucleosome. Intact nucleosomes migrate much higher than free DNA. The agarose gel result shows almost all of 601 DNA wrapped histone octamer has assembled to form nucleosomes.)

Western Blot (WB)
(Western Blot for activity detection of Mononucleosomes (H3.1) 2 ug Recombinant Mononucleosomes (H3.1) were incubated with different concentrations of DOT1L in reaction buffer for 3 hours at room temperature, respectively. Western blot was used to detect the generation of reaction products (H3K79me1).Recombinant Histone Octamers were used as control substrates. The Western Blot result showed that nucleosomes were more suitable substrate for DOT1L than histone octamers.)

Related Product Information for Mononucleosomes recombinant protein
Short Description: Recombinant Mononucleosomes (H3.1) consist of a 167 bp of 601 DNA without any tag and two molecules each of histones H2A that includes amino acids 1-130 (end)(accession number NM_003512), H2B that includes amino acids 1-126 (end)(accession number NM_003518), H3.1 that includes amino acids 1-136 (end)(accession number NM_003529), and H4 that includes amino acids 1-103 (end)(accession number NM_003548). All of these histones were expressed in E Coli. The molecular weight of histone octamer is 108 kDa. Nucleosomes comprise the smallest subunit of chromatin; they consist of 147 bp of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3 and H4). Therefore, nucleosomes are more physiologically relevant substrates than histones and histone-derived peptides for use in 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.

Product Notes
The Mononucleosomes (Catalog #AAA389129) is a Recombinant Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Mononucleosomes, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
