Pre-coated

1.Bring all kit components and samples to room temperature (18-25 °C) before use.
2.Standard - Reconstitute the Standard with 1.0 mL of Standard Diluent, kept for 10 minutes at room temperature, shake gently.
3.Dilute Detection Reagent A and Detection Reagent B to the working concentration 100-fold with Assay Diluent A and B, respectively.
4.Wash Solution - Dilute 20 mL of Wash Solution concentrate (30x) with 580 mL of deionized or distilled water to prepare 600 mL of Wash Solution (1x).
5.TMB substrate - Aspirate the needed dosage of the solution with sterilized tips and do not dump the residual solution into the vial again.

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.

Average the duplicate readings for each standard, control, and samples and subtract the average zero standard optical density. Construct a standard curve by plotting the mean O.D. and concentration for each standard and draw a best fit curve through the points on the graph or create a standard curve on log-log graph paper with target concentration on the y-axis and absorbance on the x-axis.

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level of target were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level of target were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV < 10%
Inter-Assay: CV < 12%
