This Week in the Product Spotlight: "The Matrix Reloaded: Revolutions in Research"

Probing the Matrix

As featured in our current sale and PepTalk, the Matrix Metalloproteinases (MMPs) are zinc-dependent endoproteinases.1 MMPs are involved in the degradation of the extracellular matrix (ECM) and are thought to provide a pathway for invasion by cancerous tumor cells. Peptides International carries both the MMP substrates and inhibitors as well as the proteinases themselves.

The TAPI (TNF-Alpha Protease Inhibitor) analogs have been shown to block TNF-α processing and also to inhibit L-selectin action by inhibiting the formation of a key precursor protein. They are inhibitors for Collagenase, MMP, and α-Tumor Necrosis Factor.

MMP substrates, on the other hand, are used in spectrophotometric assays of many matrix metalloproteinases. The table below is a useful cross-reference the MMP substrates that are carried by Peptides International.

For a complete list of MMP products, click here to view them on the Peptides International website. Specific substrates and inhibitors can also be synthesized by design to meet your research needs.
