Recognizes the ~92 kDa latent and the ~83 kDa active forms of MMP9.
Does not react with MMP1, MMP2, MMP3 or MMP13.
The antibody recognizes precursor (92 kDa) and active (83 kDa) forms of human and guinea pig MMP-9.
Breast carcinoma tissue.
Conditioned medium of human fibrosarcoma HT1080 cells
The protein is secreted so you may need to concentrate the protein from cell culture media. Concentrate protein by TCA, acetone or ammonium sulphate precipitation.
HL60 cell lysate, U937 cell lysate, HT1080 cell lysate, human spleen lysate
Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C long term. Avoid freeze / thaw cycle.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 2 µg/ml.
Use at an assay dependent concentration. PubMed: 22496779
Use a concentration of 2 µg/ml. Detects a band of approximately 92 kDa (predicted molecular weight: 78 kDa).
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.
Produced by normal alveolar macrophages and granulocytes.
Belongs to the peptidase M10A family. Contains 3 fibronectin type-II domains. Contains 4 hemopexin repeats.
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.
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.

ab58803 staining MMP9 in murine rib sections by Immunohistochemistry (Frozen sections). Tissue was fixed with paraformaldehyde and permeabilized using 0.1% Triton. Samples were then blocked with 20% serum for 1 hour at 19°C followed by incubation with the primary antibody at a 1/100 dilution for 16 hours at 4°C. An Alexa Fluor®488-conjugated donkey anti-mouse polyclonal (green) (ab150105) was used as secondary antibody at a 1/200 dilution. Counterstain DAPI (blue).

Immunofluorescence analysis of murine neural stem cells, staining MMP9 (red) with ab58803. Cells were fixed in paraformaldehyde and blocked and permeabilized with 0.1% Triton-X and 10% goat serum. Cells were incubated with primary antibody and an AlexaFluor®568-conjugated goat anti-mouse IgG (ab175473) was used as the secondary antibody.
