      Intended use

      This ELISA kit applies to the in vitro quantitative determination of Rat MMP-9 concentrations in serum, plasma and other biological fluids.

      Test principle

      This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat MMP-9. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat MMP-9 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat MMP-9, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat MMP-9. You can calculate the concentration of Rat MMP-9 in the samples by comparing the OD of the samples to the standard curve.

      Specificity

      This kit recognizes Rat MMP-9 in samples. No significant cross-reactivity or interference between Rat MMP-9 and analogues was observed.

      Typical data

      As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, washing technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data is provided below for reference only.

      Precision

      Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat MMP-9 were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat MMP-9 were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Rat MMP-9 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 93-106 100
      EDTA plasma (n=5) 91-104 98
      Cell culture media (n=5) 88-102 95

      Linearity

      Samples were spiked with high concentrations of Rat MMP-9 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
