The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-Fr Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.


  • Function

    Plays a role in the regulation of glomerular permeability, acting probably as a linker between the plasma membrane and the cytoskeleton.
  • Tissue specificity

    Almost exclusively expressed in the podocytes of fetal and mature kidney glomeruli.
  • Involvement in disease

    Defects in NPHS2 are the cause of nephrotic syndrome type 2 (NPHS2) [MIM:600995]. It is a renal disorder characterized clinically by childhood onset of proteinuria, hypoalbuminemia, hyperlipidemia, and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. The disorder is resistant to steroid treatment and progresses to end-stage renal failure in the first or second decades. Some patients show later onset of the disorder.
  • Sequence similarities

    Belongs to the band 7/mec-2 family.

  • Immunohistochemical analysis of paraffin-embedded human kidney tissue labeling NPHS2 with ab229037 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) ready to use. Positive staining on human glomeruli and weak staining on renal tubules (PMID: 21499232; PMID: 24559085; PMID: 11786407) is observed. Counter stained with hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) ready to use.

    Heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab229037).
