Technical Guide to Chromatin Immunoprecipitation: Critical Factors for Success
Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms. Epigenetic regulation allows a cell to vary its response based on its biological and environmental contexts. Epigenetic changes can effect transcriptional and post-transcriptional regulation via mechanisms such as histone modification, chromatin and nucleosome remodeling, DNA methylation, and small and non-coding RNA-mediated regulation. These mechanisms, in cooperation with transcription factors and other nucleic acid-binding proteins, regulate gene expression. Epigenetic mechanisms of gene regulation impacts diverse areas of research—from agriculture to human health. Common epigenetic assays such as chromatin immunoprecipitation (ChIP) and RNA immunoprecipitation (RIP) rely on high quality antibodies that recognize specific epigenetic modifications for accurate results. EMD Millipore offers over 100 ChIPAb+™ and RIPAb+™ validated antibody kits that are quality tested on ChIP/RIP assays and are conveniently provided with control qPCR primers and negative control antibodies to ensure first time ChIP/RIP success.

"Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms instead of by alterations in DNA sequence. These changes can be cell- or tissue-specific, and can be passed on to multiple generations. Epigenetic regulation enriches DNAbased information, allowing a cell to vary its response across diverse biological and environmental contexts. Although epigenetic mechanisms are primarily centered in the nucleus, these mechanisms can be induced by environmental signals such as hormones, nutrients, stress, and cellular damage, pointing to the involvement of cytoplasmic and extracellular factors in epigenetic regulation."
