Tetranucleosomes assembled from full-length recombinant human histones. Histone octambers are assembled into tetranucleosomes by standard methods with an 844 bp DNA comprising four repeats of a strong nucleosome positioning sequence. Each tetranucleosome unit will thus contain 8 copies each of the four histones, plus the 844 bp DNA, for a total MW of 985 kDa.
NOTE: Each vial contains 50 µg nucleosomal DNA,
determined by A260nm. Given the assembly ratio of 211
bp/nucleosome, the total weight, DNA + protein, is 89.7 µg.
A 50 ug vial of RBC Recombinant Nucleosomes
contains over 75% more product than those from vendors that sell by total
STORAGE: -70°C. Thaw quickly and store on ice before use. The remaining, unused, undiluted portion should be snap frozen, for
example in a dry/ice ethanol bath or liquid nitrogen. Minimize freeze/thaws if possible, but very low volume aliquots (<5 µl) or storage of
diluted solutions are not recommended.
