Histone Variants ChIP-chip arrays

Histone Variants (Lieb project, Lieb subgroup)

General Description

Chromatin was prepared from C. elegans embryos and cross-linked with formaldehyde. Sonicated chromatin was immunoprecipitated with an affinity-purified polyclonal anti-HTZ-1 antibody. 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. The median of four normalized log2(ratios) are shown in this track. Ref: PMID 18787694
