ChIP-on-chip (also known as ChIP-chip) is a technology that combines chromatin immunoprecipitation ('ChIP') with DNA microarray ("chip"). Like regular ChIP, ChIP-on-chip is used to investigate interactions between proteins and DNA in vivo. Specifically, it allows the identification of the cistrome, the sum of binding sites, for DNA-binding proteins on a genome-wide basis. Whole-genome anal… WebThe principle of ChIP is simple: the selective enrichment of a chromatin fraction containing a specific protein. An antibody is used to immunoprecipitate a protein of interest together with its associated DNA. It is then recovered and analyzed for example by PCR, microarrays or sequencing to find out at what genomic loci the protein was bound to. iran political current eventsWebChromatin immunoprecipitation (ChIP) assays identify links between the genome and the proteome by monitoring transcription regulation through histone modification … iran political philosophy
