Product Overview
This rabbit polyclonal antibody detects PR domain zinc finger protein 2 (gene PRDM2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 188.9 kDa, and the supplier reports an observed band at about 280 kDa.
PRDM2, also called RIZ1, is a PR-domain zinc finger protein with histone methyltransferase activity toward lysine 9 of histone H3. It can bind DNA and regulate gene transcription and is considered a tumor suppressor that is often silenced in cancers. PRDM2 is studied in chromatin regulation and cancer.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HeLa cells, human K562 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human rectum adenocarcinoma tissue, human testicular seminoma tissue, mouse testis tissue, rat testis tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): U2OS cells.
Samples with a confirmed signal (flow cytometry): HepG2 cells.
Immunogen
Recombinant human PRDM2 fragment (Met1–Gln1378), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places PR domain zinc finger protein 2 in the nucleus. Tissue expression noted by UniProt (human): Highly expressed in retinoblastoma cell lines and in brain tumors. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
