This assay has high sensitivity and excellent specificity for detecting Rat MMP9 (Matrix Metalloproteinase 9). The assay range is from 4.7 to 300 ng/ml (Sandwich kit) with a sensitivity of 1.8 ng/ml. There is no detectable cross to reactivity with other relevant proteins. Activity loss rate and accelerated stability test ect have been conducted to guarantee the best performance of the products after long storage and delivery.

• High sensitivity and specificity
• Perfect reproducibility and consistency across batches
• Quality control with three-level inspections
• Wide range of targets/species available
• Intra-Assay: CV <10%, Inter-Assay: CV <12%

MMP-9 (also known as gelatinase B) is secreted as a 92 kDa zymogen. Cleavage of pro-MMP-9 at or near residue 87 results in the active enzyme with a mass of approximately 82 kDa. MMP-9 has three fibronectin type II domains, a hemopexin-like domain and a proline-rich type V collagen-homologous domain. Pro-MMP-9 can be activated by MMP-3 or by certain bacterial proteinases. MMP-9 is inhibited byα2-macroglobulin or by TIMP-1, which binds to pro-MMP-9 as well as to active MMP-9.Pro-MMP-9 is secreted by monocytes, macrophages, neutrophils, keratinocytes, fibroblasts, osteoclasts, chondrocytes, skeletal muscle satellite cells, endothelial cells, and various tumor cells. Pro-MMP-9 expression is upregulated by TGF-β1, IL-1β, TGF-α, PDGF-AB,
