Description
Short Description: Recombinant Mononucleosomes H3.3 (K4I)-biotin consist of a 167 bp of 601 DNA with 5' biotin tag and two molecules each of histones H2A that includes amino acids 1-130 (end)(accession number NM_003512), H2B that includes amino acids 1-126 (end)(accession number NM_003518), H3.3 that includes amino acids 1-136 (end)(accession number NM_005324) with a point mutation Lys4Ile, and H4 that includes amino acids 1-103 (end)(accession number NM_003548). All of these histones were expressed in E Coli cells. The molecular weight of the histone octamer is 108 kDa. Recombinant Mononucleosomes H3.3 (K4I)-biotin are suitable for use as substrates for histone modification enzymes, or to generate chromatin in vitro
