Re-ChIP screening of the factors recruited to the pS2 promoter by apo-ERα isoforms. Chromatin prepared from α-amanitin synchronized MDA-MB231 cells expressing ERα66 (A) or ERα46 (B) was subject to the ChIP procedure with the antibodies shown at the left side, and again immunoprecipitated using antibodies shown at the top of the panels. (C) Scheme illustrating the topology of the complexes recruited to the pS2 promoter, as indicated through the comprehensive Re-ChIP analysis shown above.
