Detection of Human 11 beta ‑HSD2 by Western Blot. Western blot shows lysates of human kidney tissue, human placenta tissue, and human colon tissue. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human 11 beta ‑HSD2 Monoclonal Antibody (Catalog # MAB8630) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for 11 beta ‑HSD2 at approximately 40 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
11 beta ‑HSD2 in Human Kidney. 11 beta ‑HSD2 was detected in immersion fixed paraffin-embedded sections of human kidney using Mouse Anti-Human 11 beta ‑HSD2 Monoclonal Antibody (Catalog # MAB8630) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to convoluted tubules.

Background: 11 beta-HSD2
The human enzyme HSD-2/11 beta-HSD2 is encoded by the HSD11B2 gene and codes for a 405 aa protein, with high expression in kidney, colon, pancreas and placenta1. HSD-2 modulates intracellular glucocorticoid levels by catalyzing the conversion of cortisol to the inactive metabolite cortisone2. HSD-2 is abundantly expressed in human placenta and controls fetal glucocorticoid levels to protect the fetus from glucocorticoid exposure. Similarly, HSD-2 expression in the distal nephron protects mineralcorticoid receptors from glucocorticoids and helps regulate blood pressure3. Exposure to major environmental pollutant like Cadmium, inhibits activity of HSD-2 which affects the synthesis of glucocorticoids in placenta and thus contribute to developing preeclamptic conditions.
