  • Tested applicationsSuitable for: WB, ICC/IF, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    A synthetic peptide made to the C-terminus of mouse Cathepsin E.

  • Positive control
    • Murine reticulocyte lysate. Cathepsin E is expressed abundantly in the stomach, Clara cells and alveolar macrophages of the lung, brain microglia, spleen, and activated B lymphocytes. It is not expressed in resting B lymphocytes.



Our Abpromise guarantee covers the use of ab36996 in the following tested applications.

WB 1/1000. Predicted molecular weight: 42 kDa.
ICC/IF 1/200.
IHC-P Use at an assay dependent concentration.


  • FunctionMay have a role in immune function. Probably involved in the processing of antigenic peptides during MHC class II-mediated antigen presentation. May play a role in activation-induced lymphocyte depletion in the thymus, and in neuronal degeneration and glial cell activation in the brain.
  • Tissue specificityExpressed abundantly in the stomach, the Clara cells of the lung and activated B-lymphocytes, and at lower levels in lymph nodes, skin and spleen. Not expressed in resting B-lymphocytes.
  • Sequence similaritiesBelongs to the peptidase A1 family.
  • Post-translational
    Glycosylated. The nature of the carbohydrate chain varies between cell types. In fibroblasts, the proenzyme contains a high mannose-type oligosaccharide, while the mature enzyme contains a complex-type oligosaccharide. In erythrocyte membranes, both the proenzyme and mature enzyme contain a complex-type oligosaccharide.
    Two forms are produced by autocatalytic cleavage, form I begins at Ile-54, form II begins at Thr-57.
  • Cellular localizationEndosome. The proenzyme is localized to the endoplasmic reticulum and Golgi apparatus, while the mature enzyme is localized to the endosome.

    Predicted band size : 42 kDa
    Observed band size : 42 kDa
  • ab36996 staining Cathepsin E at a dilution of 1/2000 in Human stomach and tonsil tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). The sections were PFA-fixed and subjected to Heat-mediated antigen retrieval in TRIS EDTA Buffer pH 9.0 and permeabilization with DAKO wash buffer with Tween. The primary antibody was diluted 1/2000 in DAKO blocking dilution buffer and incubated with the sample for 30 minutes at 20°C. An HRP-conjugated Goat anti-Rabbit polyclonal was used as the secondary antibody.
