The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Use a concentration of 1 µg/ml. Detects a band of approximately 74 kDa (predicted molecular weight: 78 kDa).
Defects in Bile salt activated lipase (CEL) are a cause of maturity onset diabetes of the young type 8 with exocrine dysfunction (MODY8) [MIM:609812], also known as diabetes and pancreatic exocrine dysfunction (DPED). MODY [MIM:606391] is an autosomal dominant form of diabetes mellitus. The pancreas serves both endocrine and exocrine functions. The endocrine cells are found in the islets of Langerhans. They synthesize insulin and other hormones, and are involved in the pathogenesis of diabetes mellitus. The exocrine cells produce bicarbonate and digestive enzymes and are involved in the pathogenesis of pancreatic malabsorption. The localization of the islets within exocrine pancreatic tissue is suggestive of an interdependency and cross talk between these two cell populations in their normal and in their abnormal function.
We hypothesize that the 74 kDa band represents the mature form of Bile salt-activated lipase, which has had its signal sequenced cleaved off.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Bile salt-activated lipase antibody (ab79131)
IHC image of Bile salt-activated lipase staining in mouse pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab79131, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
