Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 45 kDa.
IHC-P 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • Application notesIs unsuitable for ICC or IP.
  • Target

    • FunctionThiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis.
    • Tissue specificityExpressed in larger amounts in spleen and lung. Detected in liver, heart, small intestine, colon, thymus, prostate, skeletal muscle, peripheral blood leukocytes, kidney and testis. No expression in the brain.
    • Sequence similaritiesBelongs to the peptidase C14A family.
      Contains 1 CARD domain.
    • Post-translational
      The two subunits are derived from the precursor sequence by an autocatalytic mechanism.
    • Cellular localizationCytoplasm.

    • Immunohistochemical staining of paraffin embedded human kidney with purified ab108362 at a dilution of 1/500. A pre-diluted HRP polymer for rabbit/mouse IgG was used as the secondary antibody and the sample was counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.
