Mononucleosomes (H2AZ.1), Human Recombinant

SKU: 16-1014
Pack Size: 50 μg
Mononucleosomes (H2AZ.1), Human Recombinant Description: Mononucleosomes assembled from recombinant human histones expressed in E. coli (two each of histones H2AZ.1, H2B, H3 and H4. Accession numbers: H2AZ.1-P0C0S5; 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. H2AZ.1 and H2AZ.2 are variants of histone H2A and implicated in diverse cellular functions ranging from transcriptional regulation, chromosome transmission and DNA damage repair. H2AZ has a dedicated deposition machinery (the SWR-C ATPase).

Mononucleosomes (H2AZ.1), Human Recombinant Formulation: Purified recombinant mononucleosomes (50 µg total mass, 27.4 µg in 50.0 µl) in 10 mM Tris-HCl pH 7.5, 1 mM EDTA, 25 mM NaCl, 2 mM DTT, & 20% glycerol. Nucleosome molecular weight = 198,425.5 Da.

Mononucleosomes (H2AZ.1), Human Recombinant Storage and Stability: Stable for six months at -80°C from date of receipt. For best results, aliquot and avoid multiple freeze/thaws.

Mononucleosomes (H2AZ.1), Human Recombinant Application Notes: Mononucleosomes (H2AZ.1), 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 (H2AZ.1), Human Recombinant do not contain free DNA which could alter assayed activities.
