WB
Western blot analysis of 5-methylcytosine (5-mC) on different conjugations with Mouse anti-5-methylcytosine (5-mC) antibody at 1/1,000 dilution.
Lane 1: Uridine-BSA (negative)
Lane 2: Cytidine-BSA (negative)
Lane 3: 5-Methylcytosine-BSA (positive)

Lysates/proteins at 2 μg/Lane.
Exposure time: 14 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/1,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Mouse IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human colon tissue with Mouse anti-5-methylcytosine (5-mC) antibody at 1/200 dilution.
The section was denatured in 2M HCl for 15 minutes at room temperature, then neutralized in 0.1M Tris-HCl (pH 8.3) for 10 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/200 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
