Human anti-TNF-α Antibody(Anti Tumor Necrosis Factor Alpha Antibody) 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-TNF-α Antibody 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-TNF-α Antibody in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

- 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.

- Recovery
-
Add a certain amount of anti-TNF-α Antibody into the sample. Calculate the recovery by comparing the measured value with the expected amount of anti-TNF-α Antibody in the sample.
