En teknik för identifiering av specifika DNA-sekvenser, bundna, in vivo, till proteiner av intresse. Metoden omfattar formaldehydfixering av kromatin för att korslänka DNA-bindande proteiner med DNA. Sedan DNA klippts upp i små fragment isoleras specifika DNA-proteinkomplex med hjälp av immunprecipitering med proteinspecifika antikroppar.
A technique for identifying specific DNA sequences that are bound, in vivo, to proteins of interest. It involves formaldehyde fixation of CHROMATIN to crosslink the DNA-BINDING PROTEINS to the DNA. After shearing the DNA into small fragments, specific DNA-protein complexes are isolated by immunoprecipitation with protein-specific ANTIBODIES. Then, the DNA isolated from the complex can be identified by PCR amplification and sequencing.
