Product Description

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.

Our recombinant nucleosomes are now an even better value than before. Due to our constant efforts to innovate and improve our manufacturing processes, we can now offer more (80% more) of our industry-leading recombinant nucleosomes for the same price.

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.
