Immunohistochemistry analysis of MMP2 showing staining in the cytoplasm and membrane of paraffin-embedded human breast tissue (right) compared to a negative control without primary antibody (left). To expose target proteins, antigen retrieval was performed using 10mM sodium citrate (pH 6.0), microwaved for 8-15 min. Following antigen retrieval, tissues were blocked in 3% H2O2-methanol for 15 min at room temperature, washed with ddH2O and PBS, and then probed with a MMP2 monoclonal antibody (Product # MA1-779) diluted in 3% BSA-PBS at a dilution of 1:20 overnight at 4°C in a humidified chamber. Tissues were washed extensively in PBST and detection was performed using an HRP-conjugated secondary antibody followed by colorimetric detection using a DAB kit. Tissues were counterstained with hematoxylin and dehydrated with ethanol and xylene to prep for mounting.

MA1-779 contains 100 ug of in vitro produced, protein A purified antibody (1 mg/ml) in PBS containing 1 mg/ml BSA and 0.05% sodium azide.
MA1-779 has been successfully used in Western blot applications. By Western blot, MA1-779 detects a ~66 kDa band representing purified recombinant human MMP-2.
The MA1-779 immunogen is activated rhMMP-2.
The matrix metalloproteinases (MMPs) are a family of at least eighteen secreted and membrane-bound zincendopeptidases. Collectively, these enzymes can degrade all the components of the extracellular matrix, including fibrillar and non-fibrillar collagens, fibronectin, laminin and basement membrane glycoproteins. In general, a signal peptide, a propeptide, and a catalytic domain containing the highly conserved zinc-binding site characterizes the structure of the MMPs.
