Applications
Our Abpromise guarantee covers the use of ab73734 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
| Application | Abreviews | Notes |
|---|---|---|
| IHC-P | Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. | |
| WB | Use a concentration of 1 µg/ml. Detects a band of approximately 95 kDa (predicted molecular weight: 78 kDa).Can be blocked with Human MMP9 peptide (ab73733). |
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
modificationsProcessing 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

Western blot - Anti-MMP9 antibody (ab73734)Anti-MMP9 antibody (ab73734) at 1 µg +Recombinant Human MMP9 protein (Proenzyme) (ab82955) at 0.1 µg
Secondary
Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 78 kDa
Exposure time: 2 minutesThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 5% Bovine Serum Albumin before being incubated with ab73734 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406,

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-MMP9 antibody (ab73734)IHC image of MMP9 staining in human colon carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab73734, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Western blot - Anti-MMP9 antibody (ab73734)Anti-MMP9 antibody (ab73734) at 1 µg/ml + Human spleen tissue lysate - total protein (ab29699) at 10 µg
Secondary
Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
Performed under reducing conditions.
Predicted band size: 78 kDa
Observed band size: 95 kDa why is the actual band size different from the predicted?
Additional bands at: 40 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 12 minutes
The 95 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to MMP9.
