Information on standard material:
The standard might be recombinant protein or natural protein, that will depend on the specific kit. Moreover, the expression system is E.coli or yeast or mammal cell. There is 0.05% proclin 300 in the standard as preservative.
Information on reagents:
The stop solution used in the kit is sulfuric acid with concentration of 1 mol/L. And the wash solution is TBS. The standard diluent contains 0.02 % sodium azide, assay diluent A and assay diluent B contain 0.01% sodium azide. Some kits can contain is BSA in them.
Information on antibodies:
The provided antibodies and their host vary in different kits.
- 100 μL
- 3 h
- Prepare all reagents, samples and standards,
- Add 100μL standard or sample to each well. Incubate 1 hours at 37 °C,
- Aspirate and add 100μL prepared Detection Reagent A. Incubate 1 hour at 37 °C,
- Aspirate and wash 3 times,
- Add 100μL prepared Detection Reagent B. Incubate 30 minutes at 37 °C,
- Aspirate and wash 5 times,
- Add 90μL Substrate Solution. Incubate 10-20 minutes at 37 °C,
- Add 50μL Stop Solution. Read at 450nm immediately.
- Aufbereitung der Reagenzien
- Bring all kit components and samples to room temperature (18-25 °C) before use.
- Standard - Reconstitute the Standard with 1.0 mL of Standard Diluent, keep for 10 minutes at room temperature, shake gently (not to foam). The concentration of the standard in the stock solution is 20 ng/mL. Prepare 7 tubes containing 0.5 mL Standard Diluent and produce a double dilution series. Mix each tube thoroughly before the next transfer. Set up 7 points of diluted standard such as 20 ng/mL, 10 ng/mL, 5 ng/mL, 2.5 ng/mL, 1.25 ng/mL, 0.625 ng/mL, 0.312 ng/mL, and the last microcentrifuge tube with Standard Diluent is the blank as 0 ng/mL.
- Detection Reagent A and Detection Reagent B - Briefly spin or centrifuge the stock Detection A and Detection B before use. Dilute to the working concentration with Assay Diluent A and B, respectively (1:100).
- Making serial dilution in the wells directly is not permitted.
- Prepare standard within 15 minutes before assay. Please do not dissolve the reagents at 37 °C directly.
- Please carefully reconstitute Standards or working Detection Reagent A and B according to the instruction, and avoid foaming and mix gently until the crystals are completely dissolved. To minimize imprecision caused by pipetting, use small volumes and ensure that pipettors are calibrated. It is recommended to suck more than 10μL for once pipetting.
- The reconstituted Standards, Detection Reagent A and Detection Reagent B can be used only once.
- Contaminated water or container for reagent preparation will influence the detection result.
- Aufbereitung der Proben
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.
