Description

Human I-TAC (Interferon Inducible T-cell Alpha Chemoattractant) CLIA Kit

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 I-TAC . 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 I-TAC 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 I-TAC, 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 I-TAC. The concentration of Human I-TAC in the samples can be calculated by comparing the RLU of the samples to the standard curve.

Specificity

This kit recognizes Human I-TAC in samples. No significant cross-reactivity or interference between Human I-TAC 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 I-TAC were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human I-TAC were tested on 3 different plates, 20 replicates in each plate.
