Merck, IM36-100UG, Anti-MMP-3 (Ab-1) Mouse mAb (55-2A4)

General description
Purified mouse monoclonal antibody (see application references). Recognizes the ~59/57 kDa latent and the ~45/28 kDa active forms of MMP-3 and MMP-3/TIMP complexes (see application references).
Recognizes the ~57/59 kDa latent and the ~28/45 kDa active forms of MMP-3. Will also recognize MMP-3/TIMP-1 complexes. Slightly cross-reacts (~34%) with human MMP-10.
This Anti-MMP-3 (Ab-1) Mouse mAb (55-2A4) is validated for use in Frozen Sections, Immunoblotting, Paraffin Sections for the detection of MMP-3 (Ab-1).

This antibody has 34% cross-reactivity with human MMP-10. For paraffin sections, staining can be enhanced by culturing tissue in 2 µM monensin for 3 h. Pre-treating with trypsin or a pressure cooker may enhance staining. Tissue can then be fixed with PLP (perioddate-lysine-4% paraformaldehyde) and stained using 5-10 µg/ml MMP-3 antibody. See application references for more information. Clone 55-2A4 is called Clone B in Obata, K., et al. To prepare conditioned medium for positive control, incubate HT-1080 cells for 2 h at 37°C in serum-free media containing 100 nM PMA. Collect and centrifuge medium; concentrate as necessary. Store in aliquots at -20°C. Antibody should be titrated for optimal results in individual systems.
