Product details:
Abcam MMP8 Inhibitor Screening Assay Kit (Colorimetric) (ab139452) is a complete assay system designed to screen MMP8 inhibitors using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC
). The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5'-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (e=13,600 M
at pH 6.0 and above). The assays are performed in a convenient 96-well microplate format.
This kit is useful to screen inhibitors of MMP8, a potential therapeutic target. The MMP inhibitor NNGH is also included as a prototypic control inhibitor.
Thiol inhibitors should not be used with this kit, as they may interfere with the colorimetric assay.

Matrix metalloproteinase-8 (MMP-8) also known as neutrophil collagenase is an enzyme with a molecular weight of approximately 57 kDa. It belongs to the matrix metalloproteinase family which is involved in the breakdown of extracellular matrix components. MMP-8 mainly expresses in neutrophils but can also be found in other tissues such as the skin lungs and liver. The expression of MMP-8 increases during inflammation and infection where it plays a critical role in tissue remodeling and repair processes.
Biological function summary
MMP-8 participates in the degradation of collagen types I II and III contributing to extracellular matrix remodeling. It acts independently rather than being part of a larger enzyme complex. Its activity is tightly regulated by tissue inhibitors of metalloproteinases (TIMPs) to prevent excessive tissue damage. By modulating the extracellular matrix MMP-8 influences processes like wound healing cell migration and angiogenesis indicating its essential role in maintaining tissue homeostasis.
Pathways
MMP-8 plays a role in the inflammatory response and wound healing pathways. It interacts with and processes other proteins like pro-inflammatory cytokines and growth factors which are important for regulating these pathways. MMP-8 collaborates with matrix metalloproteinase-9 (MMP-9) in the inflammatory pathway to facilitate leukocyte migration and rapid tissue remodeling during acute inflammatory responses. Its regulation involves complex interactions among proteolytic enzymes emphasizing its function in balancing matrix degradation and formation.
MMP-8 is associated with periodontal disease and rheumatoid arthritis. In periodontal disease elevated MMP-8 levels can lead to breakdown of connective tissue and bone contributing to tooth loss. In rheumatoid arthritis MMP-8 alongside MMP-1 degrades joint cartilage collagen exacerbating the inflammation and joint damage. These associations underline MMP-8's potential as a biomarker for these diseases and highlight the need for MMP-8 testing tools such as MMP8 ELISA kits to monitor disease progression and treatment efficacy.
