一般描述
Chromatin Immunoprecipitation (ChIP) is a powerful technique for mapping the in vivo distribution of proteins associated with chromosomal DNA. These proteins can be histone subunits and post-translational modifications or other chromatin associated proteins such as transcription factors, chromatin regulators, etc. Additionally, ChIP can be used to identify regions of the genome associated with these proteins, or conversely, to identify proteins associated with a particular region of the genome. ChIP methodology often involves protein-DNA and protein-protein cross-linking, fragmentation of the cross-linked chromatin, and subsequent immunoprecipitation of chromatin with an antibody specific to a target protein. The DNA fragments isolated in complex with the target protein can be identified by a variety of methods including PCR, DNA microarray and DNA sequencing. Standard or quantitative PCR can be performed to verify whether a particular DNA sequence (the gene or region of the genome) is associated with the protein of interest. The combination of ChIP and promoter or genomic tiling microarrays (ChIP-chip) allows genome-wide identification of DNA-binding sites for chromatin-associated proteins with precise resolution. Alternatively, high-throughput sequencing of libraries constructed from immunoprecipitated chromosomal DNA (ChIP-Seq) is a powerful alternative to ChIP-chip in mapping the protein-DNA interactions across mammalian genomes.
Chromatin Immunoprecipitation (ChIP) is an important technique allowing the researcher to analyze in vivo interactions of proteins with genomic DNA. Any chromatin-associated or DNA binding protein can be analyzed with this technique, provided a good antibody to the protein exists. One can measure different proteins localized to a specific region of the genome, or the genome wide distribution of a specific protein. Another powerful application of this technique is to analyze changes in histone modifications that correlate with processes like transcription, mitosis or DNA repair.
Features & Benefits:
Faster:Magnetic protein A beads allow for the entire ChIP protocol to be done in as little as a day! All reagents to process your samples are included - you don′t have to spend valuable time making them.
Easier:Spin columns make DNA purification easier and more reliable - no more messy phenol-chloroform extractions.
Greater Reproducibility:Positive and negative control antibodies and PCR primers are included to help validate your results and to troubleshoot your experiments.
