Detection of Mouse Uromodulin by Western Blot.
Western blot shows lysates of mouse kidney tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Mouse Uromodulin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5175) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Uromodulin at approximately 115 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Uromodulin in Mouse Kidney.
Uromodulin was detected in immersion fixed frozen sections of mouse kidney using Sheep Anti-Mouse Uromodulin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5175) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to convoluted tubule epithelial cells. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Uromodulin (also Tamm-Horsfall glycoprotein or THP) is a 105‑120 kDa urinary glycoprotein. It is secreted by renal tubule epithelium, acts as a binding protein for IL‑1, TNF-alpha and C1q, activates resting monocytes, and promotes neutrophil phagocytosis. Uromodulin forms high molecular weight oligomers that line the kidney tubules. Mouse Uromodulin is GPI-linked. Its proprecursor is 619 amino acids (aa) in length. It contains three EGF-like domains (aa 28‑148), a ZP domain that mediates oligomerization (aa 335‑590), and a cleavable C-terminal propeptide (aa 619‑642). There are multiple splice variants. One shows an alternate start site at Met343, and there are two substitutions, a 17 aa substitution for aa 601‑642, and a 166 aa substitution for aa 441‑642. Over aa 25‑618, mouse Uromodulin shares 78% and 89% aa identical to human and rat Uromodulin, respectively.
