Purification of nanogram-range immunoprecipitated DNA in ChIP-seq utility Chromatin immunoprecipitation-sequencing (ChIP-seq) is a broadly used epigenetic strategy for investigating genome-wide protein-DNA interactions in cells and tissues. (chipready.com)
ChIP can be used to answer a multitude of scientific questions involving the interaction of proteins and chromatin. (cellsignal.com)
The principle behind ChIP is relatively straightforward and relies on the use of an antibody to isolate, or precipitate, a certain protein, histone, transcription factor, or cofactor and its bound chromatin from a protein mixture that was extracted from cells or tissues. (cellsignal.com)
Because antibodies are raised against unfixed antigens, N-ChIP offers the advantage of better recognition and binding of antibodies to their target antigens. (cellsignal.com)
In X-ChIP, chemical fixatives such as formaldehyde are used to crosslink the protein of interest to the DNA and fragmentation of chromatin is achieved through sonication or nuclease digestion. (cellsignal.com)
X-ChIP also minimizes the chances of chromatin protein loss during extraction, allowing for the detection of transient protein interactions. (cellsignal.com)
It is optimized for ChIP reactions with chromatin from 10 6 cells (up to ~50 μg DNA), and can also be scaled up (or several preparations pooled) to accommodate 10 8 cells for genome-wide binding studies in ChIP-chip and ChIP-Seq applications. (sigmaaldrich.com)

Unlike ChIP, DamID does not require a specific antibody against the protein of interest. (wikipedia.org)

Miniaturization of the assay into microwell formats facilitates automation and increases concentration of the antigen (target transcription factor) during the IP workflow - this avoids the "dilution effect" of low antigen concentrations that favor dissociation of the antibody:antigen complex 4 and decrease the efficiency of ChIP. (abcam.com)
The Abcam high-sensitivity ChIP assay employs a unique chimeric protein to capture the antibody-bound protein:DNA complex and this offers significant advantage: the capture protein is smaller than Protein A or G and is coated at high density on the surface of microtiter plate wells, providing a much higher number of IgG immobilization sites in a smaller area, which in turn ensures efficiency and concentration of eluted DNA. (abcam.com)
