Description

Introduction to UMOD Antibody

The UMOD antibody is a polyclonal or monoclonal immunoglobulin designed to specifically bind to the Uromodulin protein. UMOD is expressed in renal tubular cells, particularly in the thick ascending limb of the loop of Henle, and plays roles in water impermeability, infection defense, and mineral homeostasis . The antibody is widely used in immunological assays to study UMOD’s biological functions and its involvement in kidney diseases.

UMOD Protein Characteristics

  • Molecular Weight: 80–90 kDa

  • Domains: EGF-like, D8C, and zona pellucida domains

  • Function: Forms a gel-like barrier in the TAL, binds pathogens (e.g., E. coli), and regulates magnesium and uric acid excretion

Techniques

TechniqueApplication
Western Blot (WB)Detects UMOD in lysates of renal cells (e.g., IMCD3) and urine

Target Background

Function
Uromodulin plays a crucial role in the biogenesis and organization of the apical membrane of epithelial cells in the thick ascending limb of Henle's loop (TALH). It promotes the formation of a complex filamentous gel-like structure, potentially contributing to the water barrier permeability. Uromodulin may serve as a receptor for binding and endocytosis of cytokines like IL-1, IL-2, and TNF. It facilitates neutrophil migration across renal epithelia. In urine, uromodulin contributes to colloid osmotic pressure, hinders the passage of positively charged electrolytes, prevents urinary tract infections, and inhibits the formation of liquid containing supersaturated salts, thereby preventing the subsequent formation of salt crystals.
