Acute post-streptococcal glomerulonephritis (APSGN) is an infection- triggered glomerulonephritic disease (Reference 1). Nephritis-Associated Plasmin receptor (NAPlr) is an intracellular component of hemolytic streptococcus that induces nephritis. Glomerular NAPlr deposition is frequently found in infection-related glomerulonephritis (IRGN), especially in glomerulonephritis that is triggered by streptococcal infection (i.e. streptococcal-infection related nephritis [SIRN]). Glomerular NAPlr deposition is not found in non-infection-related nephritis.
Therefore, Immunostaining using anti-NAPlr antibody is ideal for identifying IRGN and SIRN (References 2-5). Although a distinct commercially available anti-NAPlr monoclonal antibody (1F10) has been in use, it is claimed to suffer from low sensitivity in Immunostaining. By contrast, staining sensitivity is better with polyclonal anti-NAPlr antibodies. However, stable generation and supply of this pAb is difficult because of the complicated step of NAPlr extraction from streptococcal particles. This new polyclonal antibody against an NAPlr peptide was established to balance both satisfactory sensitivity in Immunostaining with stable antibody production.
