  Western blot - Anti-MMP9 antibody [EP1254] (ab76003)

  Blocking and diluting buffer and concentration: 5% NFDM/TBST.
  
  Exposure time: 3 seconds; 40 seconds.
  
  Anti-GAPDH antibody [EPR16891] - Loading Control ab181602 was used as loading control for GAPDH.
  
  Although MMP9 has been studied in brain in some publications, ab76003 was unable to detect signal in normal brain tissue， this may because MMP9 expression level is low in normal brain and would be increased in abnormal conditions like injury (PMID: 31198417).

  Western blot - Anti-MMP9 antibody [EP1254] (ab76003)

  MMP9 Western blot staining using rabbit Anti-MMP9 antibody

  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 [EP1254] (ab76003; 5 microgram per mL) overnight at 4°C. Antibody binding was detected using infrared labeled goat anti-rabbit (green) antibody (diluted 1:20000) for 1 hour at room temperature before imaging.

  The expression of MMP-9 can be stimulated by various agents, such as inflammatory cytokine, growth factor, and 12-O-tetradecanoylphorbol-13-acetate (TPA) (PMID:21047770, 28969043).

  Based on our preliminary data, ab76003 detects no or weak band of interest in the untreated cell lines at the dilution of 1/200. Treatment increasing the expression of MMP-9 is recommended when using this antibody.

  Functional Study - Anti-MMP9 antibody [EP1254] (ab76003)

  Unpurified ab76003 staining MMP9 in U87-MG cells treated with domoic acid (ab120338), by ICC/IF. Increase of MMP9 expression correlates with increased concentration of domoic acid, as described in literature.
  The cells were incubated at 37°C for 6h in media containing different concentrations of ab120338 (domoic acid) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with unpurified ab76003 (1/200) dilution was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight^® 488 anti-rabbit polyclonal antibody (Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  OI-RD Scanning - Anti-MMP9 antibody [EP1254] (ab76003)

  We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody.
  Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.
