Abstract: A type IV collagen-like immunoreactive peptide and an antibody thereof which are useful for detecting nephritis, a method for selecting a type IV collagen-like immunoreactive peptide, a method for screening an immunoreactive antibody and an immunoreactive peptide, a nephritis model, a method for detecting chronic nephritis, a vaccine, and a therapeutic agent for nephritis are provided. A type IV collagen-like immunoreactive peptide immunologically reacts with an isolated, chronic nephritis-derived biological sample. Preferably, the type IV collagen-like immunoreactive peptide includes at least one member selected from the group consisting of at least one chain selected from alpha 1 to alpha 6 chains as a constituent alpha chain, at least one region selected from 7S, the central helical domain, and NC1 as a constituent region, and a peptide having 3 to 35 amino acids as a constituent peptide.

Abstract: The present invention dedicates to detect nephritis in early stage of either primary or secondary nephritis using an anti NC1 monoclonal antibody. The present invention dedicates to provide useful information for diagnosis of renal function to detect NC1 by immunofluorescent stain method in renal biopsy section obtained at early stage where immunoglobulins do not deposit yet in renal GBM etc, or by antigen-antibody reaction in urine or serum specimens. Furthermore, the present invention comprises to utilize for therapeutic use.
