Chromatin immunoprecipitation of NKAP at the p21 promoter. 293:Gal4-TK-luc cells were transfected with Gal4DBD or Gal4DBD-NKAP and ChIP was performed using anti-Gal4. DNA recovered by ChIP was compared with input DNA from each transfection by Q-PCR to measure the quantity of p21 promoter or upstream genomic sequence. Data shown are from 3 independent immunoprecipitations. Error bars show SD.
