Core Histones ChIP-chip arrays

Core Histones (Lieb project, Ahringer subgroup)

General Description

Synchronized C. elegans early embryos from strain N2 were treated with the cross-linking reagent formaldehyde. Sonicated chromatin was prepared and immunoprecipitated with an affinity-purified polyclonal antibody that recognizes core histone H3. After whole genome amplification, NimbleGen genomic tiling microarrays were used in two-color hybridization experiments to compare the signal from the input DNA versus the fragments pulled-down in the ChIP. Normalized log2(ratios) are shown in this track.
