Assay Procedure
1.Add 100μL each of dilutions of standard, blank and samples into the appropriate wells, respectively. Cover with the Plate sealer. Incubate for 1 hour at 37 °C.
2.Remove the liquid of each well, don't wash.
3.Add 100μL of Detection Reagent A working solution to each well, cover the wells with the plate sealer and incubate for 1 hour at 37 °C.
4.Aspirate the solution and wash with 350μL of 1x Wash Solution to each well and let it sit for 1-2 minutes. Remove the remaining liquid from all wells completely by snapping the plate onto absorbent paper. Totally wash 3 times. Invert the plate and blot it against absorbent paper.
5.Add 100μL of Detection Reagent B working solution to each well, cover the wells with the plate sealer and incubate for 30 minutes at 37 °C.
6.Repeat the aspiration/wash process for total 5 times as conducted in step 4.
7.Add 90μL of Substrate Solution to each well. Cover with a new Plate sealer. Incubate for 10 - 20 minutes at 37 °C. Protect from light.
8.Add 50μL of Stop Solution to each well. Mix the liquid by tapping the side of the plate.
9.Remove any drop of water and fingerprint on the bottom of the plate. Then, run the microplate reader and conduct measurement at 450nm immediately.
Calculation of Results
Average the duplicate readings for each standard, control, and sample and subtract the average zero standard optical density. Create a standard curve by reducing the data using computer software capable of generating a four parameter logistic (4-PL) curve-fit.
Handling Advice
The kit should not be used beyond the expiration date on the kit label.
Do not mix or substitute reagents with those from other lots or sources.
If samples generate values higher than the highest standard, dilute the samples with Sample Diluent and repeat the assay.
Any variation in Sample Diluent, operator, pipetting technique, washing technique, incubation time/temperature and kit age can cause variation in binding.
This assay is designed to eliminate interference by soluble receptors, binding proteins and other factors present in biological samples. Until all factors have been tested in the Immunoassay, the possibility of interference cannot be excluded.
Storage Comment
The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 °C upon being received. The other reagents can be stored at 4 °C.
