Glomerular basement membrane (GBM) is the basal lamina layer of glomerulus which can be found in the kidney. The GBM, glomerular capillary endothelial cells and filtration slits (between podocytes) all are vital in performing the function of filtrating of the glomerulus, this separates the blood present in the capillaries from the filtrate (formed in the Bowman’s capsule). The GBM is essentially a fusion of the podocyte basal laminas and the endothelial cell. The GBM is made up of three layers: the lamina rara externa which is adjacent to podocyte processes, lamina densa which is the dark central zone and the lamina rara interna which is adjacent to endothelial cells. The glomerular membrane is made up of mesangial cells and modified pericytes which can separate capillaries from each other in other parts of the body. The podocytes which are responsible for adjoining them contain filtration slits with a diameter 25nm (formed by pseudopodia). The pathological condition which have been associated with GBM include: Goodpasture’s syndrome (which can also be called anti-glomerular basement membrane disease), Nephrotic syndrome, diabetic glomerulosclerosis and Alport syndrome. ELISA assay have now been developed which consist of the corresponding pure antigen are able to display specificities and sensitivities up to 99%.
Human GBM ELISA kit can be used for in-vitro quantitative analysis of IgG autoantibodies against glomerular basement membrane (GBM) in human plasma and serum. This assay has a minimum analytical sensitivity limit of 1.0 U/ml.
The minimum detection sensitivity level of human glomerular basement membrane (GBM) using this human GBM ELISA kit was 1.0 U/ml. The dynamic assay range for this kit is 20.0 – 200.0 U/ml.
