Product Summary for Rat Total MMP-9 Quantikine ELISA Kit
The Quantikine Rat Total MMP-9 Immunoassay is a 4.5 hour solid phase ELISA designed to measure total rat MMP-9 (Pro-, active, and TIMP-complexed MMP-9) in cell culture supernates, serum, and plasma. It contains NS0-expressed recombinant rat MMP-9 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant protein. Results obtained using natural rat MMP-9 showed dose-response curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural rat MMP-9.

Recovery for Rat Total MMP-9 Quantikine ELISA Kit
The recovery of rat MMP-9 spiked into various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Samples (n=4) | 94 | 87-107 |
| Platelet-poor Heparin Plasma (n=4) | 92 | 80-103 |
| Serum (n=4) | 97 | 90-115 |
Linearity
To assess the linearity of the assay, samples containing high concentrations of rat MMP-9 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: MMP-9
MMP-9 (Gelatinase B) is a metalloproteinase that degrades multiple extracellular matrix components including Gelatin, Collagens III, IV, V, and XI, Elastin, Nidogen-1, and Vitronectin. It also cleaves a variety of chemokines and growth factors (e.g. IL-1 beta, CXCL8/IL-8, CXCL7, CXCL4, CXCL1, Latent TGF-beta, membrane bound TNF-alpha, VEGF, and FGF basic), Amyloid beta peptide, Substance P, and Myelin Basic Protein. MMP-9 can trigger signaling through various transmembrane proteins or inhibit signaling by inducing their shedding from the cell surface (e.g. CD44, E-Cadherin, Integrins, ICAM-1, and CD25/IL-2 R alpha). The activity of MMP-9 is regulated by its association with the TIMP-1 protease inhibitor. Circulating levels of MMP-9 are elevated in many inflammatory disorders including intraluminal thrombus formation, atherosclerosis, Crohn’s disease, hepatitis C virus infection, colorectal cancer, and Duchenne muscular dystrophy.
