Abstract


Glomerulonephritis disease is characterized by inflammation of glomeruli or small blood vessels in the kidney which causes kidney diseases. Glomerulonephritis disease deposits the anti-GBM auto antibody in the glomerular basement membrane. The type IV collagen is the main component of glomerular basement membrane that has α3 chain of type (IV) collagen of non-collagenous domain which contains N-terminal 7S domain, a triple helical collagenous domain, and a C- terminal non-collagenous glomerular domain (NC1). The amino terminal of α3 (IV) NC1 that induces the experimental autoimmuno glomerulonephritis (EAG) in rat model has been identified. The recombinant rat α3 (IV)NC1 antigen has nine amino acid span that is consistent with antibody or T cell epitope which is induced in EAG. The research is carried out on the recombinant rat α3 (IV) NC1 production, purification, quantification, and characterization. The circulation of Anti-GBM antibody in glomerular basement membrane can be measured by the ELISA assay. In addition, the recombinant rat antigen is secreted in HEK293 cell supernatant which is purified by Anti-FLAG M2 monoclonal IgG antibody affinity column. In addition, it is characterized and quantified by SDS-PAGE gel electrophoresis and Western blotting techniques.
