Chromatin Immunoprecipitation (ChIP) Assay Kit

Protein and nucleic acid interaction reagents and resources for investing protein-RNA, protein-DNA, and protein-protein interactions and associated applications.

The 3rd edition of An Introduction to Antibodies and Their Applications provides a concise overview of some of the key features for the use of antibodies and immunochemical techniques in biological research. This handy reference guide supplements the techniques described in literature, recorded in general laboratory procedures, and described on individual product data sheets. Antibody design, development, and production are our expertise. Stringent validation of our antibodies is only one component of a comprehensive process we undertake to provide the antibodies most cited by the research community (see section Antibody Quality on page 2 for an in-depth look at our expertise).

"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."
