WB
Western blot analysis of MMP-9 on different lysates with Rabbit anti-MMP-9 antibody at 1/5,000 dilution.
Lane 1: THP-1 whole cell lysate (20 µg/Lane)
Lane 2: THP-1 treated with 200nM TPA for 10 minutes whole cell lysate (20 µg/Lane)
Lane 3: Rat lung tissue lysate (20 µg/Lane)
Lane 4: Rat spleen tissue lysate (20 µg/Lane)
Exposure time: 2 minutes;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/5,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1:100,000 dilution was used for 1 hour at room temperature.
IHC
Immunohistochemical analysis of paraffin-embedded human tonsil tissue with Rabbit anti-MMP-9 antibody at 1/1,000 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/1,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
FC
Flow cytometric analysis of MMP-9 was done on A431 cells. The cells were fixed, permeabilized and stained with the primary antibody (1/50) (red). After incubation of the primary antibody at room temperature for an hour, the cells were stained with a Alexa Fluor 488-conjugated Goat anti-Rabbit IgG Secondary antibody at 1/1000 dilution for 30 minutes.Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
