Rat IFN-γ(Interferon γ) ELISA Kit
This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti IFN-γ antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with IFN-γ bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again 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 IFN-γ in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

- Assay Procedure Summary
-
- Step 1: Add 100ul standard or sample into each well, seal the plate and statically incubate for 90 minutes at 37°C.
- Washing: Wash the plate twice without immersing.
- Step 2: Add 100ul biotin-antibody working solution, seal the plate and statically incubate for 60 minutes at 37°C.
- Washing: Wash the plate three times and immerse for 1min each time.
- Step 3: Add 100ul HRP-Streptavidin Conjugate (SABC) 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.
- Standard Curve
-
This product is detected by QC department and meets performance required in the manual. (Laboratory Humidity: 20%-60%; Temperature: 18°C -25°C; Equilibrate TMB substrate to 37°C before staining. After adding into the ELISA wells, incubate for 15min at 37°C in dark.)
Due to different assay environments and operations, assay data below and standard curve are provided for reference. Experimenters should establish standard curve according to their own assay.
