CONTROL SYSTEM FOR IMMUNOPRECIPITATION STUDIES

摘要

The, present invention provides for uses of a nanoparticle e.g. a virus or virion, preferably a bacteriophage, for providing control in an immunoprecipitation reaction with a recognition molecule, wherein an epitope peptide is displayed oh said naripparticle, e.g. by said virus or virion and recognized by said recognition molecule in the immunoprecipitation reaction. The nanoparticle carries a nucleic acid comprising a sequence encoding said epitope. Preferably, the immunoprecipitation is chromatin immunoprecipitation (ChIP).
