Background

JMJD2b (UniProtKB/Swiss–Prot entry O94953), belongs to the JMJD2 family of histone demethylases which play an important role in the establishment of the histone code. JMJD2b specifically demethylates the trimethylated K9 of histone H3. It is not able to demethylate K4, K27 and K36 of histone H3, nor K20 of histone H4.

Storage/Stability

Store at –80°C for up to 2 years. Centrifuge after first thaw to maximize product recovery. Aliquot to avoid repeated freeze/thaw cycles. Aliquots may be stored at –20°C for at least one month.

Assay Conditions

Determination of the titer
To determine the titer, an ELISA was performed using a serial dilution of the antibody directed against human JMJD2b (Cat. # 25297). The wells were coated with the peptide used for immunisation of the rabbit. By plotting the absorbance against the antibody dilution (Figure 1), the titer of the antibody was estimated to be 1:3,000.

Western blot analysis using the antibody directed against JMJD2b
Nuclear extracts of HeLa cells (40 µg) were analyzed by Western blot using the antibody against JMJD2b (Cat. # 25297) 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.

Immunofluorescence using the antibody directed against JMJD2b
HeLa cells were stained with the antibody against JMJD2b (Cat. No. 25297) and with DAPI. Cells were fixed with 4% formaldehyde for 10 minutes and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labelled with the JMJD2b antibody (left) diluted 1:200 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.
