Mononucleosomes (H3.3G34V), Recombinant Human Biotinylated
SKU: 16-0347 Pack Size: 50 μg
Mononucleosomes (H3.3 G34V), Recombinant Human Biotinylated Description: Recombinant human histone H3.3 (H3F3A, H3.3A, H3F3, accession P84243) containing a methionine at position 4, expressed in E. coli. Histone H3 is one of the four proteins that are present in the nucleosome, the basic repeating unit subunit of chromatin, consisting of 147 base pairs of DNA wrapped around an octamer of core histone proteins (H2A, H2B, H3 and H4). H3.3 is a histone variant, a non-allelelic replacement histone found in regions of high chromatin turnover outside of S-phase (e.g. at actively transcribed genes). The substitution of V for G at position 34 is associated with pediatric diffuse intrinsic pontine gliomas (DIPGs) with and diminished levels of H3K36 methylation. The 601 sequence, identified by Lowary and Widom, is a 147-base pair sequence that has high affinity for histone octamers and is useful for nucleosome assembly and contains a 5' biotin-TEG group.

Western Blot Data: Western analysis of Mononucleosomes (H3.4G34V), Recombinant Human. Top Panel: Wildtype H3.3 (Lane 1) and H3.3G34V containing nucleosomes (Lane 2) were probed with an anti-H3.3G34V antibody. Only the H3.3G34V sample produced a detectable signal. Bottom Panel: Detail from Coomassie stained gel of Western blot. (Click image to enlarge)
