      Intended use

      This CLIA kit applies to the in vitro quantitative determination of Human IGFBP-3 concentrations in serum, plasma and other biological fluids.

      Test principle

      This CLIA kit uses the Sandwich-CLIA principle. The micro CLIA plate provided in this kit has been pre-coated with an antibody specific to Human IGFBP-3. Standards or samples are added to the micro CLIA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human IGFBP-3 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 Human IGFBP-3, biotinylated detection antibody and Avidin-HRP conjugate will appear fluorescence. The Relative light unit (RLU) value is measured by the Chemiluminescence immunoassay analyzer. The RLU value is positively associated with the concentration of Human IGFBP-3. You can calculate the concentration of Human IGFBP-3 in the samples by comparing the RLU value of the samples to the standard curve.

      Specificity

      This kit recognizes Human IGFBP-3 in samples. No significant cross-reactivity or interference between Human IGFBP-3 and analogues was observed.

      Typical data

      As the RLU 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 Human IGFBP-3 were tested 20 times on one plate, respectively.
      Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human IGFBP-3 were tested on 3 different plates, 20 replicates in each plate.

      Recovery

      The recovery of Human IGFBP-3 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) 89-101 94
      EDTA plasma (n=5) 97-109 103
      Cell culture media (n=5) 88-100 94

      Linearity

      Samples were spiked with high concentrations of Human IGFBP-3 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
