Product Overview
This rabbit polyclonal antibody targets 3-keto-steroid reductase/17-beta-hydroxysteroid dehydrogenase 7 (gene HSD17B7) in human and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 38.2 kDa, and the supplier reports an observed band at about 38 kDa.
HSD17B7 is a bifunctional enzyme with two roles: it reduces estrone to estradiol, and it acts as the 3-ketosteroid reductase of cholesterol biosynthesis. Through this second role it is needed for sterol production, and it is studied in steroid hormone metabolism and cholesterol synthesis.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Rat) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human HL-60 cells, human 293T cells, human Jurkat cells, human RT4 cells, rat liver tissue, rat lung tissue, rat RH35 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 liver cancer tissue, human prostate cancer tissue, human colorectal adenocarcinoma 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): HepG2 cells.
Samples with a confirmed signal (flow cytometry): Jurkat cells.
Immunogen
Recombinant human HSD17B7 fragment (Leu16–Leu336), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places 3-keto-steroid reductase/17-beta-hydroxysteroid dehydrogenase 7 in the endoplasmic reticulum membrane. Tissue expression noted by UniProt (human): Highly expressed in adrenal gland, liver, lung and thymus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
