Chromatin immunoprecipitation (ChIP) analysis of differentially expressed genes. Whole brain nuclear extracts from 4 wk old wild-type and B-allele mutants were used for ChIP. Lane M, 100 bp ladder; lane 1, Mecp2-mutant chromatin precipitated with anti-MeCP2 (negative control); lane 2, wild-type chromatin precipitated with no antibody present; lane 3, wild-type chromatin precipitated with rabbit IgG, lane 4: wild-type chromatin precipitated with anti-MeCP2, lane 5: input DNA, lane 6: no DNA control. The precipitated DNA was amplified with primers specific for the promoter regions of Fxyd1 and Reln, and for the promoter/DMR of Gtl2. The Gtl2-B amplicon is located within the Gtl2-A amplicon. Precipitation with anti-MeCP2 shows enrichment relative to the IgG and no antibody controls, indicating that MeCP2 is associated with the designated regions in vivo. As negative controls, PCR was performed using primers covering regions that do not interact with MeCP2 for each ChIP reaction (not shown).
