Description

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 DKK2. 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 DKK2 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 DKK2, 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 DKK2. You can calculate the concentration of Human DKK2 in the samples by comparing the RLU value of the samples to the standard curve.

Detection Method

Chemiluminescence

Recovery

80%-120%. The recovery of Human DKK2 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=8)	87-103	94
EDTA plasma(n=8)	90-104	98
Cell culture media(n=8)	85-98	91

Linearity

Samples were spiked with high concentrations of Human DKK2 and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.

Precision

Both intra-CV and inter-CV are < 10%.
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human DKK2 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human DKK2 were tested on 3 different plates, 20 replicates in each plate.
