Detection of Human 17 beta ‑HSD1/ HSD17B1 by Western Blot. Western blot shows lysates of human placenta tissue. PVDF membrane was probed with 0.25 µg/mL of Mouse Anti-Human 17 beta ‑HSD1/HSD17B1 Monoclonal Antibody (Catalog # MAB7178) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). 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.
Detection of Human 17 beta ‑HSD1/HSD17B1 by Simple WesternTM. Simple Western lane view shows lysates of human placenta tissue, 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 Mouse Anti-Human 17 beta ‑HSD1/HSD17B1 Monoclonal Antibody (Catalog # MAB7178). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

Background: 17 beta-HSD1/HSD17B1
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.
