Genome-wide chromatin immunoprecipitation (ChIP) studies have brought significant
insight into the genomic localization of chromatin-associated proteins and
histone modifications. The large amount of data generated by these analyses,
however, require approaches that enable rapid validation and analysis of
biological relevance. Furthermore, there are still protein and modification
targets that are difficult to detect using standard ChIP methods. To address
these issues, we developed an immediate chromatin immunoprecipitation procedure
which we call ZipChip. ZipChip significantly reduces the time and increases
sensitivity allowing for rapid screening of multiple loci. Here we describe how
ZipChIP enables detection of histone modifications (H3K4 mono- and
trimethylation) and two yeast histone demethylases, Jhd2 and Rph1, which were
previously difficult to detect using standard methods. Furthermore, we
demonstrate the versatility of ZipChIP by analyzing the enrichment of the histone
deacetylase Sir2 at heterochromatin in yeast and enrichment of the chromatin
remodeler, PICKLE, at euchromatin in Arabidopsis thaliana.
