Native Chromatin Immunoprecipitation [PDF]
, 2011 Native chromatin immunoprecipitation refers to a method that allows for identification and quantification of DNA that is associated with specific chromatin proteins without altering the structure of these proteins. The method has been used with great success in the past and has some advantages over the more widely used cross-linking chromatin ...

Methods, 2016 Chromatin immunoprecipitation (ChIP) is a valuable method to investigate protein-DNA interactions in vivo. Since its discovery it has been indispensable to identify binding sites and patterns of a variety of DNA-interacting proteins, such as transcription factors and regulators, modified histones, and epigenetic modifiers.
