Application Abreviews Notes
WB Use at an assay dependent concentration. Predicted molecular weight: 78 kDa.
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

See IHC antigen retrieval protocols.

IHC-Fr Use at an assay dependent concentration.
  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF or IP.
  • Target

    • Function
      May play an essential role in local proteolysis of the extracellular matrix and in leukocyte migration. Could play a role in bone osteoclastic resorption. Cleaves KiSS1 at a Gly-
      -Leu bond. Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide.
    • Tissue specificity
      Produced by normal alveolar macrophages and granulocytes.
    • Involvement in disease
      Intervertebral disc disease
      Metaphyseal anadysplasia 2
    • Sequence similarities
      Belongs to the peptidase M10A family.
      Contains 3 fibronectin type-II domains.
      Contains 4 hemopexin repeats.
    • Domain
      The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.
    • Post-translational
      Processing of the precursor yields different active forms of 64, 67 and 82 kDa. Sequentially processing by MMP3 yields the 82 kDa matrix metalloproteinase-9.
      N- and O-glycosylated.
    • Cellular localization
      Secreted, extracellular space, extracellular matrix.

    • This IHC data was generated using the same anti-MMP9 antibody clone, EP1255Y, in a different buffer formulation (cat# ab137867).

      Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue labelling MMP9 with purified ab137867 at 1/1000. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. A prediluted HRP-polymer conjugated anti-rabbit IgG was used as the secondary antibody. Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.
