Product Overview
This rabbit polyclonal antibody recognizes prostaglandin E synthase 2 (gene PTGES2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 41.9 kDa, and the supplier reports an observed band at about 42 kDa.
Prostaglandin E synthase 2 (PTGES2, mPGES-2) is a membrane-associated enzyme that can convert PGH2 into prostaglandin E2 in vitro. Its role in cells is debated: when bound to glutathione and heme it may instead break PGH2 down into HHT and malondialdehyde, which makes it of interest in eicosanoid metabolism studies.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HeLa cells, human Hacat cells, human MCF-7 cells, human A549 cells, rat brain tissue, mouse brain tissue.
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 breast cancer tissue, human ovarian cancer 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): HeLa cells.
Samples with a confirmed signal (flow cytometry): MCF-7 cells.
Immunogen
Recombinant human PTGES2/Gbf1 fragment (Leu100–Ile370), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places prostaglandin E synthase 2 in the Golgi apparatus membrane. Tissue expression noted by UniProt (human): Widely expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
