General description

Chromatin Immunoprecipitation (ChIP) is a widely utilized experimental technique to monitor the association of proteins with specific DNA sequences. This technique has been used to study patterns of histone modifications and to map binding sites of various proteins on a genome-wide scale with the aid of microarray technology. ChIP has also been used to determine the temporal regulation underlying the occupation of the particular chromatin locus by multiple proteins. In addition, because formaldehyde efficiently crosslinks protein to DNA as well as protein to protein, this method can, in principle, detect proteins that bind DNA directly as well as those that bind DNA indirectly through other factors.

When performing ChIP, chromatin from cells and tissues needs to be fragmented so that it becomes soluble and resolution can be achieved in detecting protein-DNA interaction at specific loci. Sonication is a common method for producing sheared chromatin. Although this method is very efficient in releasing chromatin into the solution, it has a number of limitations. For example, foaming and overheating associated with sonication can result in protein denaturation or incomplete chromatin fragmentation. Also, sonication conditions can be physically harsh and can negatively impact immunoprecipitation efficiency. These and other limitations in the procedure can make sample sonication difficult to optimize and perform reproducibly.

The EZ-Zyme Chromatin Prep kit allows ChIP analysis at nucleosome resolution by performing complete or partial digestions with a proprietary enzymatic cocktail to obtain chromatin fragments of on average one to a few nucleosomes in length. Compared to sonication, this procedure not only allows mapping the protein-DNA association at a higher resolution, but also renders the subsequent immunoprecipitation more efficient due to its mild digestion condition. In addition, enzymatic shearing is compatible with non-crosslinked ChIP (native ChIP), which allows analysis of histone modifications not only on cultured cells, but also on freshly dissected and frozen tissues.

Use:
The EZ-Zyme kit contains reagents optimized for generating enzymatically processed chromatin from mammalian cells for use in chromatin immunoprecipitation. While the kit contains a full complement of buffers required for chromatin shearing, careful attention must be paid to the details of the instructions. Follow all the instructions carefully, especially with regard to incubation times and temperatures.
