摘要:We have devised a cyclical immunoprecipitation protocol that can be used to identify and clone a specific DNA sequence that is recognized by a DNA binding protein, even if that sequence is present in only one copy in the genome of a mammal. As an example, we have used this procedure to purify mouse genomic sequences to which the simian virus 40 tumor (T) antigen binds.
