Human GBM ELISA kit can be used for in-vitro quantitative analysis of anti IgG auto-antibodies against glomerular basement membrane (GBM IgG) in human plasma and serum. This assay has a minimum analytical sensitivity limit of 1.0 U/ml.


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. The following GBM ELISA kit have now been developed which consist of the corresponding pure antigen that are able to display specificity and sensitivity up to 99%.


The minimum detection sensitivity level of IgG antibody to human glomerular basement membrane (GBM-IgG) using current human GBM ELISA kit was 1.0 U/ml. The dynamic range for this assay is 20.0 – 200.0 U/ml.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
