ChIP analysis of MeCP2-binding sites in SH-SY5Y cells. (a) Location of the amplicons in the PTPN4 gene. (b) Fold enrichment of MeCP2, no antibody and normal mouse serum ChIP from SH-SY5Y lysates across the PTPN4, JUNB and PORIN amplicons. Duplicate biological replicates were analysed in triplicate, P-values for each amplicon relative to the no antibody control (NS=not significant, **P≤0.01, ***P≤0.001). Error bars=SD.
