Application	This ELISA kit applies to the in vitro quantitative determination of Human IL-17A concentrations in serum, plasma and other biological fluids.

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 Human IL-17A. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human IL-17A 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 IL-17A, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. 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 2 nm. The OD value is proportional to the concentration of Human IL-17A. You can calculate the concentration of Human IL-17A in the samples by comparing the OD of the samples to the standard curve.

Assay Procedures

	1. Add 100L standard or sample to the wells. Incubate for 90 min at 37C
	2. Discard the liquid, immediately add 100L Biotinylated Detection Ab working solution to each well. Incubate for 60 min at 37C
	3. Aspirate and wash the plate for 3 times
	4. Add 100L HRP conjugate working solution. Incubate for 30 min at 37C. Aspirate and wash the plate for 5 times
	5. Add 90L Substrate Reagent. Incubate for 15 min at 37C
	6. Add 50L Stop Solution
	7. Read the plate at 450nm immediately. Calculation of the results
