Product Overview
JMJD2D (Jumonji domain-containing protein 2D), also known as JHDM3D or KDM4D, is a 520 amino acid protein that belongs to the JHDM3 histone demethylase family. Localized to the nucleus, JMJD2D functions as a histone demethylase that removes specific methyl residues from Histone H3, thereby playing a crucial role in the histone code. JMJD2D binds iron as a cofactor and contains one JMJC domain and one JMJN domain, both of which are thought to exhibit enzymatic activity during chromatin remodeling events. In addition, JMJD2D forms a complex with the ligand-bound form of the androgen receptor (AR) and, through this interaction, activates AR expression. Overexpression of AR is associated with prostate cancer, suggesting that, via its ability to upregulate AR, JMJD2D may be involved in carcinogenesis.

For IHC-P, heat-induced epitope retrieval (HIER) is typically required. Recommended starting conditions: citrate buffer pH 6.0 (microwave or pressure cooker, ~20 min) for rodent samples; EDTA buffer pH 9.0 for human clinical samples. After retrieval, allow sections to cool gradually before proceeding to blocking. Include a KDM4D-positive tissue control (confirmed by literature or database expression data) and a negative isotype control in every run. Recommended dilution: IHC 1:25-1:100. Refer to the product datasheet for any target-specific retrieval guidance.
This antibody has been experimentally validated in: Human, Mouse, Rat. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "Recombinant protein of human KDM4D" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: PBS with 0.05% sodium azide and 50% glycerol, PH7.4. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
Polyclonal antibodies are produced from immunized animals and may exhibit some degree of lot-to-lot variation in titer, background, and sensitivity. Each production lot is tested for performance against established acceptance criteria. When transitioning to a new lot, run a side-by-side pilot comparison against your previous lot using a validated positive control sample before updating your standard protocol. If significant performance differences are observed, contact our technical support team — titer adjustments may resolve the issue in most cases.
