Galactose-deficient IgA1 (Gd-IgA1) is an immune complex that plays a critical role in IgA nephropathy. IgA nephropathy (IgAN) or Berger’s disease is the most common form of primary glomerulonephritis in Asian countries. The renal disorder occurs when IgA1 deposits in the glomeruli of the kidney. IgA1 deposition causes inflammation of the kidneys and hampers its ability to filter waste and extra fluid from the blood. In IgA nephropathy, the IgA1 is aberrantly glycosylated; it lacks a galactose residue at one or more O-glycan sites in the hinge region due to reduced activity or expression of β-1,3-galactosyltransferase (C1GALT1), an enzyme responsible for the addition of Galactose residue. In the absence of a galactose residue, IgA1 molecules are presented as autoantigens and are attacked by IgA1 glycan-specific autoantibodies. Patients suffering from IgA nephropathy have elevated levels of Gd-IgA1 in their serum. Gd-IgA1 is known to play a critical role in the progression and pathogenesis of IgA nephropathy; hence Gd-IgA1 may serve as a promising biomarker for IgA nephropathy. BioVision’s Galactose-deficient IgA1 (Human) ELISA kit quantitatively measures Galactose-deficient IgA1 in human serum, plasma, and other biological fluids. The kit is based on Indirect ELISA principle. Test samples, Standards, and Biotinylated Detection antibody are added to the wells pre-coated with the antigen and then washed with Wash Buffer. HRP-Streptavidin is added to the plate, and post-incubation any unattached conjugates are washed off by Wash Buffer. The HRP enzymatic reaction is detected using TMB-substrate. Finally, an acidic stop solution terminates the enzymatic reaction. The color developed is directly proportional to the amount of Galactose-deficient IgA1 in the sample.
