Specifications

Our Abpromise guarantee covers the use of ab155704 in the following tested applications.

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

  • Applications

    SDS-PAGE

  • Endotoxin level
    < 1.000 Eu/µg
  • Purity
    >95% by SDS-PAGE .

  • Form
    Lyophilised
  • Additional notes

    Pre-activation is required for enzymatic assays. Please dilute Human MMP-9 to 100 µg/mL in TCNB buffer (50 mM Tris, 10 mM CaCl2, 150 mM NaCl, 0.05% Brij-35 (w/v), pH 7.5), and then add p-aminophenylmercuric acetate (APMA) to a final concentration of 1 mM. Please keep the enzyme with APMA for 8-24 hour at 37°C. Please note that the optimal treatment time may need to be determined empirically.
    *100mM APMA stock solution should be prepared in DMSO. Please avoid adding high concentration APMA solution (>20mM) directly into the reaction as it tends to precipitate. A pre-dilution step is highly recommended.

Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C or -80°C. Avoid freeze / thaw cycle.

    pH: 7.40
    Constituents: 95% PBS, 5% Trehalose

    This product is an active protein and may elicit a biological response in vivo, handle with caution.

  • Reconstitution
    It is recommended to reconstitute the lyophilized protein in sterile deionized water to a final concentration of 100 µg/mL. Solubilize for 30 to 60 minutes at room temperature with occasional gentle mixing. Carrier protein (0.1% HSA or BSA) is strongly recommended for further dilution and long term storage.

  • 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
    modifications
    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.
  • Information by UniProt
