This CLIA kit can be applied to the in vitro quantitative determination of CS concentrations in serum, plasma and other biological fluids.
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 CS. 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 CS 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 CS, 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 CS. The concentration of CS in the samples can be calculated by comparing the RLU of the samples to the standard curve.
|Detection range||62.50-4000 pg/mL|
|Repeatability||CV < 15%|
This kit recognizes natural and some recombinant CS. No significant cross-reactivity or interference between CS and analogues was observed.
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.
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level CS were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level CS were tested on 3 different plates, 20 replicates in each plate.

The recovery of CS spiked to three different levels in samples throughout the range of the assay in various matrices was evaluated.
|Sample Type||Range (%)||Average Recovery (%)|
|EDTA plasma (n=5)||87-98||93|
|Cell culture media (n=5)||87-101||92|
Samples were spiked with high concentrations of CS and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
|Serum (n=5)||EDTA plasma (n=5)||Cell culture media (n=5)|
