Title:
ANTI-NC1 MONOCLONAL ANTIBODY
Document Type and Number:
WIPO Patent Application WO/2005/082940
Kind Code:
A1
Abstract:
It is intended to detect nephritis, either primary or secondary, at the early stage with the use of an anti-NC1 monoclonal antibody. Namely, data useful in diagnosing kidney functions can be provided by immunostaining a kidney biopsy sample at the early stage, wherein immunoglobulin never undergoes deposition in glomerulus or the like, and finding NC1 via an antigen-antibody reaction in a sample such as urine or serum. Further, it is intended to apply the above antibody to therapy.
