Epicypher热销产品——Mononucleosomes, Recombinant Human

 重组人单核小体，由大肠杆菌中表达的重组人组蛋白组装而成(组蛋白H2A、H2B、H3和H4各2个;Accession numbers:H2A-P04908;H2B-O60814;H3.1-P68431;H4- P62805)，缠绕着147个碱基对包含601序列DNA。核小体是染色质的基本亚基。由Lowary和Widom鉴定的601序列对组蛋白八聚体具有高亲和力，有利于核小体的组装。

产品形式: 0.84 mg/mL mononucleosome in µL 10 mM Tris-HCl pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, and 20% glycerol. (54.6 µg protein, 100 µg DNA + protein)

Figure 1: DNA Gel Data Mononucleosomes, Recombinant Human run on an agarose gel and stained with ethidium bromide to visualize DNA. Lane 1: Free DNA extracted from nucleosomes (200 ng). Lane 2: Intact nucleosomes (400 ng).

Figure 2: Protein Gel Data Coomassie stained PAGE gel of proteins in Mononucleosomes, Human Recombinant (0.5 µg) to demonstrate the purity and integrity of the histones in the preparation. Sizes of molecular weight markers and positions of the core histones (H2A, H2B, H3 and H4) are indicated.

Figure 3: HMTase Assay Data Mononucleosomes, Recombinant Human used as a substrate in a radioactive histone methyltransferase assay with (+SET8) or without (-SET8) recombinant SET8, which is an HMTase that requires nucleosomal substrates for activity.
