This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate of the kit has been pre-coated with an antibody specific to Rat DKK1. Test samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a detection antibody (biotinylated) specific for Rat DKK1 and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each well of the well and then the plate is incubated for specific time. The free conjugate is washed away by buffer. The substrate solution is added to each well. The well that contains Rat DKK1, detection antibody (biotinylated) and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is completed by the addition of stop solution and the color turns yellow. In the last, the optical density (OD) of the wells are measured by spectrophotometer at a wavelength of 450 nm ? 2 nm. The OD value comes in proportional to the concentration of Rat DKK1. The concentration is calculated for Rat DKK1 in the samples by comparing the OD of the samples with the standard curve.
Tested Sample Types: Serum, plasma and other biological fluids Assay Time: 3.5h Cross reactivity: This kit recognizes Rat DKK1 in samples. No significant cross-reactivity or interference between Rat DKK1 and analogues was observed Precision: Both intra-CV and inter-CV are < 10%.Storage and Expiry: 2-8 degree C./-20 degree C., 12 months
