Matrix metalloproteinases-9, also known as MMP-9, is a member of the matrix metalloproteinase family. Members of this family are structurally related, zinc-containing enzymes that degrade the extracellular matrix (ECM) and connective tissue proteins. Proteolytic activities of MMPs play an important role in vascular remodeling, cellular migration, and the processing of ECM proteins and adhesion molecules. MMP-9 consists of a prodomain, catalytic domain, hinge region, and hemopexin domain. MMP-9 is secreted as an inactive zymogen that becomes activated extracellularly. The most relevant natural activators of proMMP-9 are unknown. MMP-9 activation may be mediated by the removal of the prodomain by serine proteases or other MMPs, or it may be a direct response to oxidative stress, which disrupts the cysteine switch. MMP-9 is capable of processing cytokines and chemokines. For example, it is reported to release the biologically active form of vascular endothelial growth factor (VEGF), indicating that MMP-9 may play a crucial role in the formation of new blood vessels. MMP-9 participates in the migration of immune cells as demonstrated by MMP-9 knockout mice after the antigen challenge. Increased MMP-9 expression and activity has been observed to be related to various cancers, as it may contribute to the release of metastatic cells from the bulk tumor as well as their entrance at the site of metastasis by degrading proteins in the ECM and basement membrane.

• Learn more about our Recombinant Proteins. - 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) = 10^6/ ED50 (ng/mL)
