產(chǎn)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.
