H3

Drosophila Core Histone H3 Binding Sites (Henikoff Lab). Chromatin was prepared from Drosophila S2 cells engineered to express histone H3 tagged in vivo with biotin. After digestion with micrococcal nuclease and collection with streptavidin-coated beads, NimbleGen genomic tiling microarrays were used in two-color hybridization experiments to compare the signal from the input DNA versus the fragments pulled-down by the streptavidin beads. Scaled log2(ratios) are shown in this track. [PMID: 17347439]
