SKU: 16-2103
Mononucleosomes, Recombinant, Hemi-methylated Description: Mononucleosomes assembled from recombinant histones expressed in E. coli (two each of histones H2A, H2B, H3 and H4; accession numbers: H2A-P06897; H2B-P02281; H3-Q92133; H4-P62799) wrapped by 187 base pairs of DNA containing the 601 positioning sequence DNA. The the 187 bp DNA sequence contains a 147 base-pair 601 nucleosome positioning sequence. The 601 sequence is flanked by a hemi-methylated 20 bp sequence as shown in application notes.

Mononucleosomes, Recombinant, Hemi-methylated Formulation: Mononucleosomes, Recombinant, 187x601 DNA (50 µg DNA + protein, 24.3 µg protein weight) in 52 µl 10 mM Tris pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM EDTA, 20% glycerol. Molarity = 4.32 μmolar. MW = 224,169 Da.

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