Human anti-2019 nCoV(S) IgG ELISA Kit
This kit is based on indirect ELISA detection method and takes 3h assay time. The microplate provided in this kit has been precoated with antigen. HRP-antibody is used as detection antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add HRP-detection antibody, then it binds with anti-2019 nCoV(S) IgG bound to precoated antibody. Wash unbound components and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of anti-2019 nCoV(S) IgG in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

- Required Instruments and Reagents
-
- Microplate reader (wavelength: 450nm)
- 37°C incubator (CO2 incubator for cell culture is not recommenced.)
- Automated plate washer or multi-channel pipette/5ml pipettor (for manual washing purpose)
- Precision single (0.5-10μL, 5-50μL, 20-200μL, 200-1000μL) and multi-channel pipette with disposable tips(Calibration is required before use.)
- Sterile tubes and Eppendorf tubes with disposable tips

- Assay Procedure Summary
-
- Step 1: Wash the plate twice before adding the standard and sample.
- Step 2: Add 100ul standard or sample into each well, seal the plate and statically incubate for 90 minutes at 37°C.
- Washing: Wash the plate three times and immerse for 1min each time.
- Step 3: Add 100ul HRP-antibody working solution, seal the plate and statically incubate for 30 minutes at 37°C.
- Washing: Wash the plate five times and immerse for 1min each time.
- Step 4: Add 90ul TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)
- Step 5: Add 50ul stop solution. Read at 450nm immediately and calculate.
- Stability
-
Perform the stability test for the sealed kit at 37°C and 2-8°C and get relevant data.
