Test Principle:
This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to MIγ/CXCL9. Samples (or Standards) and and Horseradish Peroxidase (HRP) linked antibody specific for MIγ/CXCL9 are added to the micro ELISA plate wells. MIγ/CXCL9 in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to MIγ/CXCL9. Excess conjugate and unbound sample or standard are washed from the plate. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of MIγ/CXCL9. You can calculate the concentration of MIγ/CXCL9 in the samples by comparing the OD of the samples to the standard curve.
Technical Data
As the OD 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 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level were tested on 3 different plates, 20 replicates in each plate, respectively.
