DNA methylation status after DNMT1 silencing in HCT116

Sample % Methylated DNA
HCT116 ctrl 5,9% ± 0,4
HCT-siDNMT1 1,95% ± 1,06

DNA extracted from cells was treated with anti-5-methylcytosine antibody, stained with the "capture antibody" and the "detection antibody" and then quantified by an EliSa-like reaction. DNA extracted from HCT-siDNMT1 cells appeared demethylated in comparison to that extracted from HCT116 cells.
