Overview

  • Product nameAnti-MMP9 antibody
    See all MMP9 primary antibodies
  • Description
    Rabbit polyclonal to MMP9
  • SpecificityThe antibody binds to Gelatinase-B, but does not cross react with the other MMP family members (MMP-1, MMP-2, MMP-3). In our hands, we observe a weaker signal in WB in human samples compared to mouse samples (BLAST of full length mouse protein sequence showed 72% homology with the Human MMP9 sequence).

Our Abpromise guarantee covers the use of ab38898 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 1/100 - 1/1000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
IHC-Fr 1/1000. (see Abreview submitted by Greg Gibson)
WB 1/1000. Detects a band of approximately 92 kDa. When using colorimetric substrates such as BCIP/NBT use at a 1/5000 dilution (for chemiluminescent substrates). Detects a band of approximately 92-95 kDa (pro-form) and 82kDa (active form) (Human samples). Mouse MMP9 is larger, and on SDS PAGE gels runs about 102-105 kDa. Dilution optimised using Chromogenic detection.
IP Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
ICC/IF 1/500.
ICC Use at an assay dependent concentration.
IHC-FoFr Use at an assay dependent concentration. PubMed: 19295156

Target

  • FunctionMay 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 specificityProduced by normal alveolar macrophages and granulocytes.
  • Involvement in diseaseIntervertebral disc disease
    Metaphyseal anadysplasia 2
  • Sequence similaritiesBelongs to the peptidase M10A family.
    Contains 3 fibronectin type-II domains.
    Contains 4 hemopexin repeats.
  • DomainThe 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.

    Performed under reducing conditions.

    This blot was produced using a 4-12% Bis-Tris gel under the MOPS buffer system. The gel was run at 200V for 60 minutes before being transferred onto a nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour before being incubated with anti-MMP9 antibody (ab38898; 2 microgram per mL)  overnight at 4°C. Antibody binding was detected using infrared labelled goat anti-rabbit (green) antibody (diluted 1:20000) for 1 hour at room temperature before imaging.

  • Anti-MMP9 antibody (ab38898) + Human MMP9

    Observed band size : 88,92 kDa (why is the actual band size different from the predicted?)
    Ab38898 detects a band at 92 Kd (pro-form) and a band at 88 Kd (active form). Mouse MMP9 is slightly larger than human MMP9, and the antibody detects a band at about 105 Kd. It is recommend to concentrate samples by Gelatin-agarose affinity chromatography prior to Western blot usage. A recommended starting concentration for Western blots is 1:1000 when using colorimetric substrates such as BCIP/NBT, and 1:5000 for chemiluminescent substrates. Higher concentration of antibody may be needed for non-human samples.

    Performed under reducing conditions.

    ab38898 detects recombinant Human MMP9 running at ~85 kDa, and endogenous full-length MMP9 in LPS-stimulated cells at ~100 kDa. This antibody also detects a band at 90 kDa in U937 PMA-treated cells. 

     

    ab38898 was incubated at 5 ug/mL and ab8245 (loading control to GAPDH) was diluted at 0.1 ug/mL and both were incubated for 48 hours at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

  • ab38898 staining MMP9 in Mouse Pancreatic carcinoma tissue sections by IHC-P (formaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% BSA for 1 hour at room temperature. Antigen retrieval was by heat mediation in citric acid (pH6). Samples were incubated with primary antibody (1/100) in 1% Aurion BSA for 12 hours. An HRP-conjugated Donkey polyclonal to rabbit IgG (1/100) was used as secondary antibody.

    Sections were incubated with primary antibody (1/500) and HRP-conjugated secondary antibody colored using DAB solution. Slides were counterstained with hematoxylin.
  • ab38898 at a 1/1000 dilution staining mouse heart tissue by Immunohistochemistry (Frozen sections). The tissue was removed from a mouse, rinsed in PBS and slowly frozen in supercooled isopentane. 14um sections were made using a cryostat. The sections were acetone fixed and blocked in 2% BSA prior to incubation with the MMP9 antibody. A Cy3 conjugated goat anti-rabbit antibody (ab6939) was used as the secondary antibody. In the image: red staining = MMP9, blue staining = nuclei, green = gelatinase activity.
