17 beta-HSD1/HSD17B1 Antibody [Unconjugated]

Western blot shows lysates of human placenta tissue. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human 17 beta ‑HSD1/HSD17B1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7178) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for 17 beta ‑HSD1/HSD17B1 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

17 beta ‑HSD1/HSD17B1 was detected in immersion fixed paraffin-embedded sections of human Alzheimer's brain using Sheep Anti-Human 17 beta ‑HSD1/HSD17B1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7178) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in neurons.

Simple Western lane view shows lysates of human placenta, loaded at 0.2 mg/mL. A specific band was detected for 17 beta ‑HSD1/HSD17B1 at approximately 40 kDa (as indicated) using 2.5 µg/mL of Sheep Anti-Human 17 beta ‑HSD1/HSD17B1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7178) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background

HSD17B1 (Hydroxysteroid 17-beta dehydrogenase type 1; also 17  beta ‑HSD1 and E2DH) is a 33-34 kDa member of the short chain dehydrogenase/reductase (SDR) superfamily of molecules. It is a cytoplasmic breast, placental and gonadal enzyme that both converts DHEA to estrogen A-diol, and inactivates DHT through oxidation and reduction. Human HSD17B1 is 328 amino acids (aa) in length. It contains an NADP binding site (aa 10-38) and a steroid catalytic site (aa 210-221). HSD17B1 functions as a 68 kDa noncovalently-linked homodimer. Over aa 2-328, human HSD17B1 shares 65% aa identity with mouse HSD17B1.
