Specificity
The 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). -

Applications
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) We recommend using Goat Anti-Rabbit IgG H&L (Cy3 ®) preadsorbed (ab6939) secondary antibody |
|
| 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. | |

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

Scale bars are 100 μm.
Immunohistochemical staining was performed on liver biopsies fixed in 4% paraformaldehyde and embedded in OCT. The frozen tissues were cut in 5 μm thick sections and stained using primary antibody against matrix metallopeptidase 9 (MMP9) (1:300, Abcam, ab38898). The nuclei were visualized with DAPI. The sections where analyzed using confocal microscopy.

Reproduced under the Creative Commons license http://creativecommons.org/licenses/by/4.0/MMP-9 immunohistochemistry in the lung tissue of a C3HeB/FeJ mouse, 10 weeks after M. tuberculosis aerosol infection. MMP-9 was visualized in macrophages (black solid arrows) and neutrophils (black dotted arrows).
Paraffin embedded sections were rehydrated in graded alcohols, steamed in citrate buffer at pH 6 and probed at room temperature for 2 hours using the MMP-9 (rabbit polyclonal; 1:250; Abcam [AB38898]) and processed with a polymer-HRP kit (BioGenex) with diaminobenzidine development and Mayer hematoxylin counterstaining. Lungs from uninfected, and infected but untreated animals without primary antibody served as negative controls. Slides were scanned using the Apeiro digital scanner (Leica).

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.

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. Goat Anti-Rabbit IgG H&L (Cy3 ®) preadsorbed (ab6939) was used as the secondary antibody. In the image: red staining = MMP9, blue staining = nuclei, green = gelatinase activity.

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.

Western blot - Anti-MMP9 antibody (ab38898)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. -
