Ready-to-use ELISA kits are available for the detection of nephrosis 1, nephrin, an alias of the protein, NPHS1 adhesion molecule, nephrin. The official gene symbol is NPHS1. The kits can detect several species variants of the protein, including: human, mouse, rat, bovine, primate, guinea pig, and other mammalian. The protein, with a mass of 134.7 kDa and length of 1241 residues, is reported to be membrane-associated. It is a member of the Immunoglobulin superfamily and may be known by other names, including: nephrin, NPHN, truncated NPHS1, renal glomerulus-specific cell adhesion receptor, nephrosis 1 congenital Finnish type (nephrin), and NPHS1 nephrin.
