SKU: 16-0009
Pack Size: 100 μg
Mononucleosomes, Human Recombinant Formulation: Mononucleosomes assembled from recombinant human histones expressed in E. coli (two each of histones H2A, H2B, H3 and H4. Accession numbers: H2A-P04908; H2B-O60814; H3.1-P68431; H4-P62805) wrapped by 147 base pairs of 601 positioning sequence DNA. The nucleosome is the basic subunit of chromatin.

Mononucleosomes, Human Recombinant Formulation: Purified recombinant mononucleosomes (100 µg total mass, protein + DNA, 54.6 µg protein) in 10 mM Tris-HCl pH 7.5, 1 mM EDTA, 25 mM NaCl, 2 mM DTT, & 20% glycerol.

Mononucleosomes, Human Recombinant Storage and Stability: Stable for six months at -20°C from date of receipt. For best results, aliquot and avoid multiple freeze/thaws.

Mononucleosomes, Human Recombinant Application Notes: Mononucleosomes, Human Recombinant are highly purified and are suitable for use as substrates in enzyme screening assays or for nucleosome binding experiments. The absence of post-translational histone modifications makes them ideal for conducting enzyme activity and screening assays.
EpiCypher Mononucleosomes, Human Recombinant do not contain free DNA which could alter assayed activities.
