Fig. 5. Methylation of histone H3 at NeuroM and NeuroD promoters as a function of
retina and optic tectum developmental stage. Quantitative ChIP experiments
were performed with an antibody specific for the dimethylated K4 of histone
H3. Results are normalized relative to the value observed for E18 retina
[NeuroM promoter (A), IP efficiency 1.2%; NeuroD promoter (B), IP efficiency
0.2%].
