Rat MMP9(Matrix Metalloproteinase 9) ELISA Kit

Matrix metalloproteinase that plays an essential role in local proteolysis of the extracellular matrix and in leukocyte migration (By similarity). Could play a role in bone osteoclastic resorption (By similarity). Cleaves KiSS1 at a Gly-, -Leu bond (By similarity). Cleaves NINJ1 to generate the Secreted ninjurin-1 form (By similarity). Cleaves type IV and type V collagen into large C-terminal three quarter fragments and shorter N-terminal one quarter fragments. Degrades fibronectin but not laminin or Pz-peptide (By similarity) Assay Type: Sandwich. Sensitivity: 1.8 ng/mL. Standard: 500 ng/mL. Detection range: 7.81-500 ng/mL. Sample type: serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids. Assay length: 3.5h. Research Field: Enzyme & Kinase,Tumor immunity,Infection immunity,Cardiovascular biology,Hepatology,. Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat MMP9. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat MMP9. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat MMP9, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat MMP9 in the samples is then determined by comparing the OD of the samples to the standard curve.
