Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that degrade components of the extracellular matrix (ECM) and play essential roles in various physiological and pathological processes such as morphogenesis, differentiation, angiogenesis, tissue remodeling, and tumor invasion. A typical MMP consists of a pro-peptide of about 80 amino acids, a catalytic metalloproteinase domain of about 170 amino acids, a linker peptide of variable lengths and a hemopexin domain of about 200 amino acids. The zinc binding motif HEXXHXXGXXH in the catalytic domain, and the ‘‘cysteine switch’’ motif PRCGXPD in the pro-peptide are common structural signatures. MMP-7, Matrilysin, is one of the smallest members of the MMP family consisting of a pro-peptide domain and a catalytic domain. It can degrade casein, laminin, fibronectin, collagen type III/IV/V/IX/X/XI, gelatin type I/II/IV/ V, elastin, and proteoglycans. MMP-7 is secreted specifically by epithelial cells and its over-expression has been observed in many tumor types such as colorectal cancer, epidermolysisbullosa associated skin cancer, bladder cancer, gastric cancers, pancreatic cancer and esophageal cancer. This enzyme serves essential functions in both innate defense and wound healing, and appears to be one of the most important MMPs in human colon cancers. It has been reported that MMP-7 contributes to tumor malignancy probably by cleaving cell surface proteins such as Fas ligand (reducing its effectiveness in triggering Fas-mediated apoptosis) and E-cadherin (disruption to the E-cadherin/beta-catenin complex results in a switch to a more invasive phenotype in cancer cells). In addition, degradation of IgG by MMP-7 may protect tumor cells from the immune system, since cleavage of IgG will remove much of the immunoglobulins' functionality.

Recommended Usage


Application Notes

Human MMP-7 Activity Assay
Human MMP-7 (hMMP-7) activity is measured by its ability to cleave a fluorogenic peptide substrate Mca-PLGL(Dpa)AR after its activation in the presence of p-Aminophenylmercuric acid. The increase of the product is monitored by increase in intensity of fluorescence at 405 nm with excitation at 320 nm.


  1. Assay Buffer: TCNB (50 mM Tris, 10 mM CaCl2, 150 mM NaCl, 0.05% Brij-35, pH 7.5)
  2. Recombinant Human MMP-7
  3. Substrate: MCa-PLGL(Dpa)AR
  4. 4-Aminophenylmercuric acetate (APMA)

Activity Assay Procedures

  1. Dilute hMMP-7 in the assay buffer at 50 µg/mL.
  2. Activate hMMP-7 by adding APMA to a final concentration of 1 mM.
  3. Incubate the activating mixture for 30 minutes at 37°C.
  4. Dilute the activated hMMP-7 to 0.4 ug/mL (0.4 ng/µL) in Assay Buffer.
  5. Dilute the substrate at 20 µM in Assay Buffer.
  6. Load into a well plate 50 μL of the 0.4 ng/μL hMM-7 and start the reaction by adding 50 μL of 20 μM Substrate. Include a substrate blank containing 50 μL Assay Buffer and 50 μL of 20 μM Substrate without any hMMP7.
  7. Read the product formation by measuring 320/405 nm (Excitation/Emission) in kinetic mode for 5 minutes.
  8. The final hMMP-7 concentration is 0.2 µg/mL (200 ng/ml, 20 ng) and the substrate is 10 µM.

How does the activity of your recombinant proteins compare to competitors?

We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!

What is the specific activity or ED50 of my recombinant protein?

The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.

Have your recombinants been tested for stability?

Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.

Does specific activity of a recombinant protein vary between lots?

Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.

How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
Use formula Specific activity (Units/mg) = 10e6/ ED50 (ng/mL)
