  • Validation Data


    Figure 1. Determination of the antibody titer
    To determine the titer of the antibody, an ELISA was performed using a serial dilution of Diagenode antibody directed against DNMT3B (Cat. No. C15410218). The plates were coated with the peptides used for immunization of the rabbit. By plotting the absorbance against the antibody dilution (Figure 1), the titer of the antibody was estimated to be 1:220,000.

    Western blot

    Figure 2. Western blot analysis using the Diagenode antibody directed against DNMT3B
    Whole cell extracts (25 μg) from HeLa cells were analysed by Western blot using the Diagenode antibody against DNMT3B (Cat. No. C15410218) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.


    Figure 3. Immunofluorescence using the Diagenode antibody directed against DNMT3B
    Human HeLa cells were stained with the Diagenode antibody against DNMT3B (Cat. No. C15410218) and with DAPI. Cells were fixed with 4% formaldehyde for 10’ and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labelled with the DNMT3B antibody (left) diluted 1:1,000 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa488. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right.

  • Target description

    DNMT3B (UniProtKB/Swiss-Prot entry Q9UBC3) catalyses the genome wide de novo methylation of CpG residues, which regulates gene expression. DNMT3B is essential for development. DNA methylation on CpG residues is coordinated with methylation of histones. Six different isoforms of DNMT3B, produced by alternative splicing, exist although isoforms 4 and 5 may not be functional due to the absence of two conserved methyltransferase motifs.
