Applications

Our Abpromise guarantee covers the use of ab79974 in the following tested applications.

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

Application Abreviews Notes
IHC-P Use a concentration of 10 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Target

  • Function
    Responsible for initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase A). It catalyzes the conversion of trypsinogen to trypsin which in turn activates other proenzymes including chymotrypsinogen, procarboxypeptidases, and proelastases.
  • Tissue specificity
    Intestinal brush border.
  • Involvement in disease
    Defects in TMPRSS15 are a cause of enterokinase deficiency (ENTKD) [MIM:226200]; a life-threatening intestinal malabsorption disorder characterized by diarrhea and failure to thrive.
  • Sequence similarities
    Belongs to the peptidase S1 family.
    Contains 2 CUB domains.
    Contains 2 LDL-receptor class A domains.
    Contains 1 MAM domain.
    Contains 1 peptidase S1 domain.
    Contains 1 SEA domain.
    Contains 1 SRCR domain.
  • Post-translational
    modifications
    The chains are derived from a single precursor that is cleaved by a trypsin-like protease.
  • Cellular localization
    Membrane.

Images

  • IHC image of Enterokinase staining in human duodenum 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 ab79974, 10µg/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.

     For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
