The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/200 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
FunctionMay be a receptor protein that acts in collecting-duct and biliary differentiation.
Tissue specificityPredominantly expressed in fetal and adult kidney. Also present in the adult pancreas, but at much lower levels. Detectable in fetal and adult liver. Rather indistinct signal in fetal brain.
Involvement in diseaseDefects in PKHD1 are the cause of polycystic kidney disease autosomal recessive (ARPKD) [MIM:263200]. ARPKD is a severe form of polycystic kidney disease affecting the kidneys and the hepatic biliary tract. The clinical spectrum is widely variable, with most cases presenting during infancy. The fetal phenotypic features classically include enlarged and echogenic kidneys, as well as oligohydramnios secondary to a poor urine output. Up to 50% of the affected neonates die shortly after birth, as a result of severe pulmonary hypoplasia and secondary respiratory insufficiency. In the subset that survives the perinatal period, morbidity and mortality are mainly related to severe systemic hypertension, renal insufficiency, and portal hypertension due to portal-tract fibrosis.
