      Intended use

      This CLIA kit can be applied to the in vitro quantitative determination of Human ECF/CCL11 concentrations in serum, plasma and other biological fluids.

      Test principle

      This kit uses Sandwich-CLIA as the method. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human ECF/CCL11. Standards or samples are added to the appropriate micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human ECF/CCL11 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human ECF/CCL11, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured spectrophotometrically by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Human ECF/CCL11. The concentration of Human ECF/CCL11 in the samples can be calculated by comparing the OD of the samples to the standard curve.

      Specificity

      This kit recognizes natural and some recombinant Human ECF/CCL11. No significant cross-reactivity or interference between Human ECF/CCL11 and analogues was observed.

      Typical data

      For convenience in result calculation, absorbance can be used as ordinate and standard concentrations as abscissa. The standard curve provided in the manual is only for reference, and experimenters should draw the standard curve based on data of themselves.

      Precision

      Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Human ECF/CCL11 were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Human ECF/CCL11 were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human ECF/CCL11 spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.

      Sample Type Range (%) Average Recovery (%)
      Serum (n=5) 93-106 101
      EDTA plasma (n=5) 88-99 94
      Cell culture media (n=5) 91-104 97

      Linearity

      Samples were spiked with high concentrations of Human ECF/CCL11 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
