- 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-2019 nCoV (S) IgM into the sample. Calculate the recovery by comparing the measured value with the expected amount of anti-2019 nCoV (S) IgM in the sample.

-
Dilute the sample with a certain amount of anti-2019 nCoV (S) IgM at 1:2, 1:4 and 1:8 to get the recovery range.
